KABUL, Oct 18: Bomb blasts killed six members of the Afghan security forces on Thursday while the US-led coalition said nine of its soldiers were wounded in an ambush in new attacks linked to a Taliban-led insurgency.

Four policemen were killed near the border with Pakistan when a remotely detonated bomb blew up their vehicle as they were patrolling a remote area of the eastern province of Khost, police said.

Three more policemen were wounded in the blast, police spokesman Wazir Badshah said without saying who might have been behind the attack.

Afghan police are on the frontline of an insurgency led by the extremist Taliban militia that was in government between 1996 and 2001.

Around 600 have been killed in violence this year, according to officials.

In another attack, two members of a militia working with the US military were killed in rugged northeastern Kunar when a bomb exploded on a road they were walking along, provincial police chief Abdul Jalal Jalal said.

The US-led coalition, which along with a NATO-headed force is in Afghanistan to help the government defeat the insurgency, announced separately that nine of its troops were wounded in an ambush in the southern province of Kandahar.—AFP
