The United States, Britain and France said Wednesday they were closing their embassies in Yemen amid the turmoil in the wake of the Shiite rebels’ takeover of the country.

The closures — which come as Yemen marks four years since the start of its own Arab Spring uprising that eventually ousted the country’s longtime autocratic ruler — were an ominous sign for the faltering U.N.-brokered negotiations between the Houthi rebels and their political rivals.

This impoverished Arabian Peninsula country has been in crisis for months, with the Iran-linked Houthis besieging the capital, Sanaa, and then taking control. In January, the rebels put U.S.-backed President Abed Rabbo Mansour Hadi and all his Cabinet ministers under house arrest, leading to their resignations. Subsequently, the Houthis — who are followers of the Shiite Zaydi sect in the Sunni-majority Yemen — dissolved parliament and declared they were taking over the government.

On Tuesday, the State Department announced it suspended operations at the U.S. Embassy in Sanaa and relocated remaining diplomatic personnel “due to the ongoing political instability and the uncertain security situation.” The embassy had been operating with only a skeleton staff for some weeks amid deteriorating conditions.

U.S. officials said the embassy’s closure would not affect counterterrorism operations against al-Qaida’s Yemen branch — considered by Washington to be the world’s most dangerous offshoot of the global terror group. Yemeni officials, however, say the move was likely to curtail U.S. military operations in the country.

Yemeni officials said Wednesday that embassy staffers destroyed files and documents and disposed of firearms belonging to the embassy guards. They also handed over Sanaa’s Sheraton Hotel, where staffers had resided for several years, to the United Nations.

Also Wednesday, Britain’s Minister for the Middle East Tobias Ellwood urged British citizens still in Yemen to “leave immediately” as his country’s embassy evacuated its staff. The French Embassy said it would close on Friday.

“The security situation in Yemen has continued to deteriorate over recent days,” Ellwood said. “Regrettably, we now judge that our embassy staff and premises are at increased risk.”

Germany urged its citizens to leave Yemen, Foreign Ministry spokesman Martin Schaefer said Wednesday.

The diplomatic missions of many Gulf Arab countries, who have backed Hadi and opposed the Houthis, have already evacuated their staff.

In Sanaa, the Houthis patrolled the streets armed with Kalashnikov rifles and dressed in a mix of police uniforms and civilian clothes. They sealed off main boulevards and drove around in pickup trucks mounted with anti-aircraft guns. Shops closed early and people mostly stayed home.

The rebels dispersed several scattered anti-Houthi protests, beating the demonstrators and attacking them with knives as they tried to march toward the U.N. offices, according to witnesses. Several people were arrested, they said. The Yemeni officials and witnesses spoke to The Associated Press on condition of anonymity because they were not authorized to talk to media.

Away from Sanaa, the Houthis pressed on with their power grab after taking control the previous day of the central province of Bayda, a gateway to the south. The Houthis now control 10 out of 22 provinces in Yemen.

Thousands flocked to the streets in the southwestern city of Taiz — Yemen’s third largest and not under Houthi control — to denounce the rebels.

The rise of the Houthis began last year when they descended from their heartland in northern Saada province, fighting their way toward the capital and defeating tribal and military rivals along the way. In September, they flooded into Sanaa, and raided major state institutions and military bases.

With Yemen military in shambles and plagued with tribal rivalries, Houthis won the backing of ousted President Ali Abdullah Saleh — himself also a Shiite Zaydi — whose loyalists in the military are suspected of enabling the Houthis’ advances.

To defuse the crisis, the United Nations has been trying to broker a power-sharing deal between the Houthis and other political forces but with little headway.

Critics say the Houthis are only buying time while making more territorial gains and setting their sights on the south, where there is a strong secessionist movement that has been demanding autonomy and a return to an independent state that existed before 1990.

The rebels’ leader, Abdel-Malek al-Houthi, warned his enemies Tuesday not to stand in his movement’s way and denounced foreign governments for removing their diplomats.

“Whoever harms the interest of this country could see that their interests in this country are also harmed,” al-Houthi said, speaking on the rebel group’s own Al-Masirah TV network.

The Houthis, traditionally based in northern Yemen along the border with Saudi Arabia, are believed to be backed by Shiite powerhouse Iran, a charge they deny.
