(CNN) -- Suspected Al Qaeda militants disguised as security forces launched an explosive assault on the U.S. Embassy in Yemen's capital, Sanaa, Wednesday killing 10 Yemeni police and civilians, officials said. The attack involved two car bombs, a spokesman for Yemen's embassy in Washington said. Six attackers, including a suicide bomber wearing an explosive vest, were also killed in the attack, Mohammed al-Basha said. There were at least four explosions -- including at least one car bomb -- and sniper fire, a senior State Department official said. Yemeni officials said the first car contained people in police uniforms who exchanged fire with Yemeni security forces, the officials said.
