A car bomb exploded on Baghdad's airport road Tuesday as a U.S. military convoy was passing by, wounding four American soldiers and destroying an armored Humvee (search), the U.S. military said.
Around 10 civilian vehicles were also wrecked in the blast on the highway leading to the capital's international airport, a police official said. He said there were civilian casualties but did not immediately have an exact figure.
Ambulances rushed at least two women, a child and three wounded men to a nearby hospital, doctors said. One of the women was covered in blood.
Maj. Phil Smith of the 1st Cavalry Division (search) said four Task Force Baghdad (search) soldiers were wounded. One of them was evacuated to a military hospital while the three others were treated on the spot.
Troops sealed off the area of the explosion as helicopters hovered overhead.
The military initially reported that a Bradley fighting vehicle was also damaged in the blast, but Smith said that the information proved to be wrong.
The treacherous stretch of road is the site of frequent attacks against U.S. troops and their supply convoys.
In a travel warning issued last week, the U.S. State Department described the airport road as among the country's most dangerous.
