The head of an international aid agency has described how nine of its workers were trapped in a fortified room as an attack by the Taliban raged around them in Afghanistan's capital. He praised the work of the Afghan police who rescued them during an eight-hour battle in one of Kabul's most upscale neighborhoods.

Richard Danziger, chief of mission for the International Organization for Migration, said Sunday he had no idea why the group was targeted. The IOM works with a United Nations mission to help resettle migrants returning to Afghanistan.

He said early reports that a Nepalese guard was killed in the Friday attack were untrue. He said five Nepalese guards were wounded, one seriously. Four IOM staff were injured including an Italian woman seriously burned by a grenade.
