The multinational toll from a suicide attack on a NATO convoy in Kabul emerged Sunday when officials said the 17 people killed included 10 Americans, two Britons, one Canadian and four Afghan nationals.

The Taliban has claimed responsibility for the car-bomb blast on Saturday, one of the deadliest attacks in Kabul during a decade of war in Afghanistan.

One of the Afghans killed was a policeman; the other three were civilians. Five of the Western victims were members of the NATO-led military force in the country, and the eight others were civilians working for coalition forces.

In another incident Saturday, three Australians working as military trainers were killed when a man wearing an Afghan National Army uniform turned his weapon on them. The gunman was killed.

NATO also reports one of its service members was killed Sunday in an insurgent attack in the south.

In the Kabul car-bomb attack, authorities initially had said all the foreigners killed were Americans. All the Western victims were aboard an armored bus driving through the Afghan capital. A man drove a car packed with explosives alongside the vehicle and triggered the fatal blast.
