KABUL, Afghanistan (AP) – NATO troops killed a civilian who did not heed their warnings to stop in southern Afghanistan, while U.S.-led coalition troops killed two militants in the east, officials said Friday.

The civilian victim was riding in a truck that was heading directly for a NATO patrol in Kandahar province Thursday, the military alliance said in a statement.

The truck failed to stop after several warnings were issued. The troops fired two shots into the vehicle, killing the civilian inside. The statement did not say whether the civilian was driving.

“Incidents such as this are very regrettable, and our thoughts are with the families and friends of the casualty,” the statement said.

Civilian deaths at the hands of foreign troops in Afghanistan are controversial and routinely worsen relations among the people, the government and the foreign troops in the country.

Separately, the U.S.-led coalition troops killed two suspected Taliban militants and detained six others during a raid in Surobi district of Kabul province, the coalition said in a statement.

The militants were killed in a gunfight after they attacked the coalition troops conducting the raid Thursday, the statement said.

A Taliban commander in the area was among the six militant’s detained, the coalition said.

Afghanistan is seeing a resurgence of violence, even as the U.S. and NATO have poured thousands of new troops into the country.

More than 4,500 people, mostly militants, have died so far this year in insurgency-related attacks.
