A suicide bomber in Afghanistan killed 13 Americans on Saturday, according to the Associated Press.

The AP report says a Taliban suicide bomber attacked an armored vehicle that was traveling as part of a convoy in Kabul. Thirteen Americans and four Afghans were killed, making it the deadliest attack in the country since August, when the Taliban shot down a NATO helicopter.

The bombing "parked a fireball and littered the street with shrapnel and twisted metal hulks," the AP reported.

NATO and Afghan forced were meeting in Kabul on Saturday to discuss the transition of power from U.S.-led coalition forces to the Afghan government. The AP described Saturday's attack as a "major setbac! k" as the U.S. scales back its military presence in Afghanistan.

The wire service said the Taliban claimed responsibility for the bombing as well as a separate suicide bombing in northwest Afghanistan. Only the bomber died in that attack.
