JALALABAD, Afghanistan (AP) _ A U.S. Marine convoy was attacked by a suicide bomber and militant ambush Sunday on a busy highway in eastern Afghanistan, and witnesses said that as the Americans sped away, they opened fire on civilian cars and pedestrians. As many as 10 people were killed and 35 were wounded.
The American military said it was unclear who was responsible for the casualties but more than a half dozen Afghans recuperating from bullet wounds told The Associated Press that the U.S. forces fired indiscriminately as they drove away along at least a six-mile stretch of one of eastern Afghanistan's busiest highways _ a route often filled not only with cars and trucks but Afghans on foot and bicycles.
A suicide attacker detonated an explosives-filled minivan as the American convoy approached, then militant gunmen fired on the troops inside the vehicles, who returned fire, the U.S. military said.
The Americans treated every car and person along the highway as a potential attacker, said Mohammad Khan Katawazi, the district chief of Shinwar.
``They were firing everywhere, and they even opened fire on 14 to 15 vehicles passing on the highway,'' said Tur Gul, 38, who was standing on the roadside by a gas station and was shot twice in his right hand. ``They opened fire on everybody, the ones inside the vehicles and the ones on foot.''
Lt. Col. David Accetta, a U.S. military spokesman, said officials were still sorting out the chain of events and could not yet say who caused the numerous deaths and injuries.
The tolls varied widely. The Interior Ministry said 10 people were killed; the provincial health chief, Ajmel Pardus, said eight died.
The U.S. military said eight civilians were killed and 35 wounded, after earlier saying 16 were killed and 24 wounded. It did not explain the revised, lower death toll, saying only that the new figures were ``the most accurate numbers to date.'' A U.S. soldier was also injured. The incident was under investigation, the military said.
``It's not entirely clear right now if the people killed or wounded by gunfire were killed or wounded by coalition forces gunfire or enemy attackers gunfire,'' Accetta said.
Interior Ministry spokesman Zemeri Bashary said the chief of the Interior Ministry's criminal division would lead a delegation to Nangarhar province on Monday to investigate. Bashary said it appeared that gunfire from the U.S. soldiers caused most of the casualties.
The gunfire from Americans prompted angry demonstrations in the region _ just 30 miles west of the Pakistan border. Hundreds of Afghans blocked the road and threw rocks at police, with some demonstrators shouting ``Death to America! Death to Karzai,'' a reference to President Hamid Karzai.
At the Jalalabad hospital, several victims said the American convoy approached them on the highway and opened fire. As the convoy neared, many cars pulled over to the side of the road, but were still hit by gunfire.
``When we parked our vehicle, when they passed us, they opened fire on our vehicle,'' said 15-year-old Mohammad Ishaq, who was hit by two bullets, in his left arm and his right ear. ``It was a convoy of three American Humvees. All three humvees were firing around.''
Ahmed Najib, 23, lay in the next bed, hit by a bullet in his right shoulder.
``One American was in the first vehicle, shouting to stop on the side of the road, and we stopped. The first vehicle did not fire on us, but the second opened fire on our car,'' Najib said, adding that his 2-year-old brother was grazed by a bullet on his cheek. ``I saw them turning and firing in this direction, then turning and firing in that direction. I even saw a farmer shot by the Americans.''
NATO and U.S. forces are often accused of firing at Afghan civilians they fear may be about to launch an attack. Though officials say the shootings are done in self defense, they often injure or kill innocent civilians. On Dec. 3, British troops speeding away from a suicide bomb attack in Kandahar city opened fire on cars, killing one civilian and wounding six others.
U.S. forces near Sunday's bombing later deleted photos taken by a freelance photographer working for The Associated Press and video taken by a freelancer working for AP Television News. Neither the photographer nor the cameraman witnessed the suicide attack or the subsequent gunfire. It was not immediately known why the soldiers deleted the photos and videos. The U.S. military did not immediately comment on the matter.
The freelance photographer, Rahmat Gul, said he took photos of a four-wheel drive vehicle where three Afghans had been shot to death inside.
An American soldier then took Gul's camera and deleted the photos. Gul said he later received permission to take photos from another soldier, but that the first soldier came back and angrily told him to delete the photos again. Gul said the soldier then raised his fist as if he was going to strike Gul.
The U.S. forces involved in the attack and ensuing gunfire were part of the U.S.-led coalition, not NATO's International Security Assistance Force. An official who asked not to be identified said the troops were Marine Special Forces.
A man claiming to speak for Hezb-e-Islami, a group he said is linked with the Taliban, claimed responsibility for the bombing and identified the attacker as an Afghan named Haji Ihsanullah in a telephone call to AP. The spokesman said that the attack was carried out by a breakaway faction of Hezb-e-Islami that was once led by Younis Khalis, a former mujahedeen commander who died last year. The group is now believed to be led by a son of Khalis.
The purported spokesman, who identified himself as Qari Sajjad, said the explosion ``destroyed two vehicles, killing or injuring American soldiers.'' Sajjad said the attack was in revenge for ``cruel acts'' done to Afghans by U.S. forces.
Accetta, the U.S. spokesman, said the attack demonstrated the militants' ``blatant disregard for human life'' by attacking forces in a populated area. NATO officials repeatedly say that suicide bombs aimed at international and Afghan forces kill far more civilians than soldiers.
Two British soldiers were killed in a rocket attack in southern Afghanistan's Helmand province, the British defense ministry said Sunday. The latest deaths bring to 50 the number of British troops killed since a U.S.-led invasion overthrew Afghanistan's Taliban regime in November 2001.
