Baghdad, Iraq ? A Reuters television sound technician was killed and a cameraman was injured Sunday while trying to cover a Baghdad gunbattle involving insurgents and U.S. troops. Police said the men were fired on by American forces.

Waleed Khaled, 35, was killed and cameraman Haider Khadem was wounded while driving to the scene of the clash in the western Baghdad district of Adil, said Alastair MacDonald, Reuters’ chief correspondent in Baghdad.

The two appear to have been targeted by a sniper, and Khadem was detained by U.S. troops after being shot, MacDonald said.

Maj. Mousa Abdul Karim of the Ghazaliyah police said U.S. soldiers opened fire on the two men near Umm al-Qura mosque.

A statement from the U.S. Army’s Task Force Baghdad said troops responded to an attack on an Iraqi police convoy that killed and wounded several officers.

“One civilian was killed and another was wounded by small-arms fire during the attack,” the statement said. “After discovering an abandoned car with explosives material, weapons and a cell phone, units began searching the area for the terror suspects who were believed to have fled on foot.”

Task Force Baghdad spokesman Lt. Col. Robert Whetstone said U.S. troops evacuated one wounded civilian from the scene, and the incident was being investigated.
