The United States is temporarily removing further staff from its embassy in the Libyan capital, the state department has said.

It said staff were being withdrawn from the Tripoli office for security reasons.

Officials said the decision would be reviewed early next week with the aim of returning staff as soon as possible.

The move follows the attack on the US consulate in Benghazi on 11 September which killed the ambassador to Libya.

Christopher Stevens and three other Americans were killed during the attack, which followed protests triggered by an amateur film made in the US which mocks Islam.

Protests against the film have spread across the Muslim world.

"This is a temporary further drawdown of staff for security reasons.

"We will review our posture again early next week with the goal of restoring staff as soon as conditions allow," a state department official said.

It was not revealed how many staff were being withdrawn from Tripoli.

A statement on the website of the US embassy in Tripoli warned that demonstrations were possible in both the capital and Benghazi on Friday.
I guess the BBC didn't get the memo.
