UN says Lebanon at risk of ‘humanitarian catastrophe’

Available for over a year

The UN says there's no longer any safe space for civilians to find refuge in Lebanon, even in Beirut. With nearly a million people displaced by the war in the country, we speak to one resident from the south who has fled his home. Also on the programme: we return to Northampton to learn how live facial recognition cameras could eventually be one part of a system to prevent crime. And we talk money, as Donald Trump is set to be the first US President to have his signature on American money.
