A Western official in Washington confirmed the US carried out a strike against suspected leaders from Al-Qaeda in the Arabian Peninsula, but said initial indications were that five people were killed. The official did not say where the strike occurred or specify whether it was carried out by a drone or a warplane.

Security across Yemen, the Arab world’s poorest country, has largely collapsed during the nearly year-old popular uprising against longtime President Ali Abdullah Saleh.

Also Tuesday, tribesmen from the Al-Mahweet kidnapped six UN workers — an Iraqi woman, a Palestinian woman, a Colombian man, a German man and two Yemeni men. The assailants demanded that the government release fellow tribesmen from prison.

Tribes in Yemen have historically used kidnapping as a way of getting concessions from the government and hostages are ordinarily well treated before being released.  Yemeni Interior Minister Ali Al-Omrani, meanwhile, escaped an assassination attempt when his car came under fire Tuesday outside the Cabinet building in the capital Sanaa, according to his spokesman Abdul-Basit Al-Qaidi.
