SANAA (REUTERS) - The United States is closing its embassy in Yemen, the Arabian peninsula state that is a front line in Washington's war against Al-Qaeda, embassy employees and US officials said on Tuesday.
US officials in Washington confirmed the embassy would close, due to the unpredictable security situation in a country where a rebel group has seized control of the capital.
The State Department declined immediate comment.
Last month, Iran-backed Shi'ite Muslim Houthi fighters, who had captured the capital in September, seized the presidential palace, driving President Abd-Rabbu Mansour Hadi and his government to resign.
After years of crisis, Yemen now risks descending into a full-blown civil war pitting regional, political, tribal and sectarian rivals against each other in a nation that shares a long border with top global oil exporter Saudi Arabia.
Yemen is home to Al-Qaeda in the Arabian Peninsula, one of the most active branches of the global Sunni Islamist group.
The United States has long conducted drone strikes on the militants, a strategy critics say has failed to make a decisive difference and has stoked anti-US sentiment.
A US defence official said a contingent of US Marines was protecting the embassy while a Navy amphibious assault ship, the USS Iwo Jima, was in the Red Sea off Yemen's coast and would be available to help with the evacuation of embassy staff, if requested from the State Department.
US officials said at least some military cooperation was continuing with Yemeni security forces but declined to speak about the embassy closure or its potential repercussions.
"Training continues and includes military skill sets such as small arms and medical," one US official said.
US officials said the Americans, who had enjoyed the support of President Hadi, have no functional relationship with the Houthi forces.
The Houthi leader, Abdel Malik al-Houti, took to the air waves to warn outside powers against interfering in the national crisis, saying in a televised speech on Tuesday it was "in the interest of every power, domestic and foreign, to stabilise this country."
"Any attempt to sow chaos or harm this country will have its repercussions on the interests of these powers," he said.
Employees of the embassy said the US mission had been getting rid of documents and weapons the past days and that the ambassador and other US staff would leave by Wednesday.
The ambassador told them Washington may ask the Turkish or Algerian embassies in Sanaa to look after US interests.
Employees at the British, French and German embassies said their missions had also been getting rid of documents and have given local staff two months' paid leave. But there was no immediate word on the missions closing down.
France's foreign ministry said it was monitoring the situation, but declined to say if the embassy would close.
Political parties have been holding talks in Sanaa under UN auspices to try to agree on a transitional administration. Two parties walked out on Monday saying they had received threats from the Houthis.
