Guinea Bissau

Guinea Bissau witnessed some dramatic events this morning when a group of army officers arrested the head of the armed forces and the prime minister, Carlos Gomer Junior.

Heavily armed troops also gained access to the UN's headquarters and questioned a former head of the navy who is staying there.

Guinea Bissau has a history of political instability and is no stranger to coups and counter-coups.

The country has also become a major transit point for cocaine trafficking between South America and Europe.

Theresa Lima, head of the BBC's Portuguese for Africa service, has been following developments and earlier spoke to Focus on Africa's Bilkisu Labaran.
