A suicide car bomber attacked an American military convoy Saturday driving on the road to Kabul's airport, killing at least one person and wounding seven, officials
said.

Two U.S. and two civilian vehicles were damaged in the attack, police said. Dozens of shops were damaged by the blast.

Health Minister Mohammad Amin Fatemi said one civilian was killed and seven others wounded, including one woman and one child.

An Associated Press reporter at the scene said he saw an injured U.S. soldier. Afghan TV reported that an American was also killed but U.S. officials said they had no reports of any deaths.

The blast came against U.S. troops responsible for training the Afghan military and police. A U.S. military spokesman said a convoy of two Humvees had been hit by the explosion but that he had no other immediate information.

U.S. military humvees arrived at the scene shortly after the 8:15 a.m. blast to secure the site and take away U.S. casualties. British troops arrived soon after that.

The blast came on a tree-lined, four-lane road that leads from the U.S. Embassy to the airport, a road frequently traveled by foreign convoys.

On Friday, U.S.-led coalition and Afghan troops clashed with insurgents during a raid in eastern Afghanistan, and civilians as well as militants were killed. In the country's volatile south, separate explosions apparently targeting NATO forces killed two children and a British soldier.
