Officials in Afghanistan say at least 10 militants and five Afghan guards were killed when Taliban militants attacked a U.S. security firm convoy in southwestern Afghanistan.
The governor of Farah province says militants Friday ambushed a convoy of a U.S.-based security company that delivers supplies to coalition forces. At least three guards were believed to have been abducted following the clash between guards and Taliban militants.
Friday's attack comes a day after a suicide bomber rammed a vehicle full of explosives into a private security convoy in the southern city of Kandahar, killing at least two people.
Also Friday, Afghanistan's Interior Ministry says three men have been arrested for allegedly giving false information to international troops, leading to U.S. air strikes that killed civilians in Azizabad village.
The arrests were based on allegations from residents of Azizabad in the western province of Herat, where Afghan and U.N. officials say U.S. air strikes killed 90 civilians, most of them children, on August 22. The U.S. has said between five and seven civilians were killed, and has since agreed to review its investigation.
Separately Friday, the U.S.-led coalition said its forces killed more than 10 militants and detained two others during two separate raids in eastern Afghanistan.
U.S. officials say the militants were killed during a raid on the compound of a militant commander in Kapisa province Thursday. In a separate operation Thursday, officials say two militants were detained during a raid on the network of Taliban commander Jalaluddin Haqqani in Khost province.
Also, two U.S. soldiers were killed in separate incidents in eastern Afghanistan Thursday.
This year has been the deadliest for American forces in the country since the 2001 U.S.-led invasion.
