Foreign Office urges British nationals to leave Yemen
British nationals in Yemen are being urged to leave the country immediately following clashes between government forces and tribal fighters in the capital.
The Foreign Secretary William Hague said he could not stress the need to leave Yemen too strongly.
More than 100 people have been killed in four days of violence.
Guardian journalist Tom Finn spoke to the BBC from the capital Sanaa and said that the clashes were beginning to die down.
