British troops are airlifted out of the capital Sana’a as the UN warns rebel advances leave the country on the brink of civil war.
Sky News understands they were airlifted from the capital Sana’a over the weekend.
They had been operating in the country alongside US counterparts, who have now also been withdrawn.
US forces evacuated al Annad airbase near the southern city of al Houta, which was captured by al Qaeda militants on Friday.
Jeff Rathke, US State Department spokesman, said in a statement: “Due to the deteriorating security situation in Yemen, the US government has temporarily relocated its remaining personnel out of Yemen.”
The UK Government has not commented on the withdrawal of British troops.
Last month, Washington, London and Paris closed their embassies as the country teeters on the brink of all-out civil war.
Yemen has become increasingly unstable amid a power struggle between Iranian-backed Shia rebels, known as Houthis, in the north and UN-recognised President Abd-Rabbu Mansour Hadi.
