Afghan and coalition forces said that they have killed six militants during a patrol in southern Afghanistan's most violent region. The US coalition said on Saturday that the combined forces were on a patrol in Helmand province Thursday when they spotted militants pulling out weapons from a hiding spot. The combined forces killed the militants and destroyed the weapons. Violence has spiked across Afghanistan the last two years. More than 6,000 people have died in insurgency-related violence in 2008, according to an Associated Press count of figures based on Afghan and Western officials.
