Ros spoke to Indians about corruption in their country, following the release of Anna Hazare, the anti corruption activist whose protest has got you talking.

It's been a difficult week for journalism, and the dust is far from settling on the News of the World scandal. It's left many asking some very difficult questions of the media. What is the media for? It's a simple question, but this affair has given it a sharp sense of urgency.

The media has long been thought of as The Fourth Estate. It's a term based on how the ancién regime in France divided society. The First Estate was the clergy, The Second Estate the nobles, and the third was everyone else. Come the eighteenth century, thinkers like Thomas Carlyle were talking about a Fourth estate, the media, which exists to hold the rest of society to account. Now if we take David Cameron at his word, the Fourth Estate is now derelict. If this is true, what can emerge from the ruins? How can the media regain people's trust? Or should we accept that an alternative is growing, with people using social media to become the world's watchdog?

They have been unable or unwilling to use this monopoly power in the public interest... Each of us must take some some fraction of the commissioning power, the power to initiate and publish inquiries.

Paul Waugh writes that many UK MPs are hoping that the events of the past few days show the decline of print media, something that will:

Permanently shift the balance away from the unelected to the elected. With most newspaper circulation charts going south, they see the broadcast media ... and even the internet as the alternative future.

But he warns us not to get too excited:

The press remains incredibly powerful, not least because it's the place that (non-phone hacked) exclusives are broken and where the sheer numbers of consumers cannot be ignored.

After all the newspaper The Guardian did lead the charge in exposing the phone hacking that was going on at The News of the World. And Wikileaks relied on newspapers to collate and present their information.

So who is The Fourth Estate today? Do you trust the media to hold politicians to account? Or is social media taking over this treasured role?

Ros spoke to people around the world about the big questions surrounding former head of the IMF Dominique Strauss-Kahn's court case in New York. Towards the end of the programme we hear the news that Mr Strauss Kahn was released from house arrest in New York, where he's been facing allegations of attempting to rape a hotel maid.

Ros talks to a panel of experts about the many questions and issues that you're raising about the Arab Uprisings. He spoke to Mahmoud Salem aka Sandmonkey, Egypt's best-known blogger, Mona Eltahawy, Arab affairs analyst and prolific tweeter, Paul Whiteway, former British diplomat in Syria, and David Ignatius, Associate Editor of the Washington Post.

We filmed this special edition from a hotel just to the side of two pyramids, on the outskirts of Cairo. Ros spoke to people about international community's response to the unrest across the Arab world, the price of these uprisings, and the role of Islam.

Today the unrest in Yemen has intensified. The presidential compound has been attacked and the President of Yemen, Ali Abdullah Saleh, has been wounded. Several other officials were also injured when at least two shells hit a mosque in the compound. It's the most significant escalation in days of fighting in Sanaa between President Saleh's forces and armed tribesmen allied to the powerful al Ahmar family. We'll be getting the latest on the situation in Yemen at 1700 GMT. Send us your questions and we'll do your best to address them. And if you're in Yemen, or worrying about your relatives in Yemen do get in touch.

Ros spoke to people from across the Balkans and around the world about the arrest of the most wanted man in Europe - former Serb general Ratko Mladic.

We also talked about the corruption scandal sweeping FIFA.

This topic was discussed on 26 May 2011. Listen to the podcast.

Police in Serbia have arrested Ratko Mladic, the former Bosnian Serb military commander who's been on the run for more than fifteen years, after being indicted for war crimes. In a news conference the Serbian president, Boris Tadic, said General Mladic had been detained on Thursday morning and the process was underway to extradite him to the International War Crimes Tribunal in the Hague. Serbian media said he was arrested with false identity documents in the northern Serbian province of Vojvodina. In 1995, he was indicted for crimes during the Bosnian war, including the genocide at Srebrenica.

The news of his arrest broke just before our early edition. We gathered reaction from the region and spoke to journalists who had covered the Bosnian War back in the nineties. You can listen to the earlier programme here.

But the discussion continues, and the internet has been flooded with comments on Ratko Mladic...

Justin in Germany writes on Facebook

Excellent news for Europe and humanity. I knew we would get him. We have to learn from the terror that has raged in europe to many times already.

But others are more sceptical. Many of you say that his arrest is a well timed political manoevre, designed to open the door to EU membership. Sandokan in Serbia posts on the B-92 webpage

This is best proof that Serbia doesn't have it's own way of thinking, we can only do something if EU tells us to.We arrested him when they told us that our EU future is was in doubt .Sad but true..

Dmitry in Moscow writes on BBC Russian.com:

It's a happy moment. But how on earth did he manage to hide for so long? It seems that Serbia didn't do anything to find him. They did it only to please the EU in the end.

But many of you are celebrating, and see this latest arrest as a sign that international justice is closing in on those suspected of war crimes. Ocaya in Uganda posts on Facebook

You can run and hide, but you can't escape. Let justice prevail and send a strong signal to the human right abusers and killers that there's no impunity.

In our 1700 GMT programme we'll be talking through the many questions raised by his arrest. Is his arrest cause for celebration or scepticism? Is this a new start for Serbia? Does his arrest show that there are no safe havens for the world's most wanted?

We discuss the key questions about the situation in Libya.

Radio is one of my first loves, and I'm currently combining it with my passion for where I live. I collect the sounds and stories of Hackney in East London, and weave them into a podcast called The Hackney Podcast. But don't worry, I'm not moonlighting. I'm part of a group of radio producers who feel the borough is rippling with life that's just got to be captured on tape. There's no money in it for us, we just do it for the love. It all comes down to being a sound junky, which is why I'm so obsessed with music. I'm into everything from Wu Tang Clan to Rachmaninov, and my best gig has to be Radiohead at Victoria Park in Hackney. That night they walked on water. I play the violin and the piano, but after watching Arcade Fire I think I've got to learn the accordion.

I don't think I've ever laughed so much at work than I do on World Have Your Say. There's something really fun about the culture of the programme. Even when you're really up against it, someone's always got a handy doughnut to keep you going. I've bumped into former WHYS producers around the BBC who refer to the programme as home. It's definitely feeling that way for me. What's there not to love about spending all day talking to you about the news?

If today we are stuck, it's not only because Europe is impotent, it's because at the Security Council, for now, China doesn't want any mention of a resolution leading to the international community's interference in a country's affairs...

All this apparent foot-dragging is making people doubt the whole purpose of the U.N.

It will be a massacre, it will be on the international community's conscience, it will be a stain on the international people... He will kill civilians, he will kill dreams, he will destroy us more and more.

She's not alone, this blogger fears the moment for action is slipping away

The time is running out, and people are giving up on the dream of removing the longest running brutal regime in the middle east

Britain's Foreign Minister Alistair Burt says it's time for "urgent" action in support of the rebels in Libya, saying it's

Imperative that something is done, and something is done today

Many are questioning the point of the U.N. So what is it for? It tries to create a forum that serves to limit future conflict on a global scale. It is built on noble ideas, such as its doctrine for "the responsibility to protect." But does it succeed in protecting the world from the atrocities that come with armed conflict? Shane Greer says that the UN has failed to meet it's high ideals because:

The UN is a political organisation draped in the cloak of international legal authority. It's designed to facilitate horse-trading based on narrow national interests rather than high-minded principle. (...) And we find that far from protecting people from the kind of atrocity it was established to prevent, the UN instead makes all the noises of caring while ultimately finding itself rendered impotent by countries whose respect for human rights is little different than one Muammar Gaddafi.

Is this fair comment? Mark Seddon says the U.N. are doing a good job. He points out that it has blazed a trail for the International Criminal Court to investigate war crimes allegations against Colonel Gaddafi. His assets have been frozen, and those of his family, effectively making Gaddaffi and his clan "house prisoners". As far as military intervention goes, Mark Seddon says:

Let's be honest, Libya is not in Europe. Military sanctions, unless agreed by the United Nations, should not include America and Europe. Indeed there is every indication that many Libyans don't want the West to become involved militarily, pointing to the disaster that was Iraq and the continuing disaster that is Afghanistan.

So is the U.N. able to protect the world? Or will it always be held back by narrow political interests? If the U.N. is all talk, what else can the world do to prevent atrocities?

The crisis in Libya continues and the world has been scrambling to find the right response. There's talk of no-fly zones, and recently the UK sent a diplomatic team, including six soldiers, out to Libya to speak to the opposition. They were detained and turned back... So what's the best way to deal with the problem? Do you think your country should support or oppose Colonel Gaddafi?

This blog post was written by Marcellin from Rwanda. The views expressed are his own and do not reflect those of the wider BBC.

The city of Kigali is growing at an appealing pace, with new buildings taking shape in a town that was once worn-out by the 1994 genocide and war. Progress is seen in many sectors, for instance the nine year basic education programme. This allows every Rwandan child to have free access to education, with their parents participating in the construction of classrooms. We're seeing progress in social infrastructures too, which are currently getting a face-lift, not just in the City, but across the country.

In its effort to end tax evasion, the government of Rwanda has enacted a law prohibiting street vending. It says such businesses impede the country's economic growth, as they are not registered and therefore don't pay taxes. Besides, with street vendors mingled in with minibuses and hundreds of motorcycles in such a small town, city officials say they have no choice but use force, since vendors don't want to operate in markets the state constructed for them as alternative.

"The so-called markets are built far from downtown, and this is where most clients are found, especially at peak-hours" one female street vendor told me. She said she'll never give up as this is the only way to get by and look after her kids. Another street hawker, a man, who sells tobacco and sweets on the road opposite my work place, told me that the rent for a stand in a market is higher than their actual income. He said they've got no alternative but to sell their wares on the street, and play a cat and mouse game with policemen.

In a developing country like Rwanda, I guess everyone has the right to earn a living, as long as it's not harmful to society. In my opinion, street vendors don't just earn a living, they also help poor communities by providing cheap goods. Besides, if policemen go on chasing these poor women selling fruits (they call it keeping the city clean) hundreds will starve, and children from poor families will drop out of school. Result? Beggars and shoplifters roaming the streets of Kigali. Is this what we want?

This topic was discussed on World Have Your Say on 2 March 2011.  Listen to the programme.

It's a human tidal wave. As I write, the Tunisian government say eighty thousand people have crossed the border into Tunisia over the past week, escaping the violence in Libya. Most of them are Egyptian migrant workers, but the refugees come from all over the world. Migrants from Sub-Saharan Africa, Vietnam, India, Bangladesh, Turkey, Tunisia, China, and the Phillippines are all scrambling to get away from the conflict in Libya.

As you can see, the needs are much much more than what is being provided there. The situation is significantly increasing and the numbers they keep flowing so there has to be massive effort not just by one country but an international effort to try to ease the situation a little bit. It's a humanitarian crisis, there has to be concerted effort and governments have to take action right now.

Ayman Gharaibeh, another UNHCR official says:

We can see acres of people waiting to cross the border. Many have been waiting for three to four days in the freezing cold, with no shelter or food.

The UNHCR is asking governments in North Africa and Europe to keep all borders open to anyone fleeing Libya. It's also asked Italy to stop sending refugees back to Libya. But Italian interior minister Roberto Maroni says they need the rest of the world to help too:

This is not just a problem for Italy, it's a problem for Europe and the world. This is a catastrophic humanitarian situation.

Various groups are trying to help at the border, including the World Food Programme, the UNHCR, Médecins Sans Frontières, and Save the Children. But in the face of such a massive exodus of people, is this enough? When it comes to taking in these refugees, which countries should shoulder the burden? Is it fair to ask governments in North Africa and Europe to keep all borders open?

We'll be looking at the situation at the border between Libya and Tunisia. Whether it's a relief worker, or a refugee, we'll try to get you in touch with those living through this crisis.
