Separate blasts in Afghanistan today killed three policemen and wounded six people including two British peacekeepers, officials said.
Afghanistan has seen a surge of attacks on Afghan and foreign forces since the Taliban announced last month they had launched a spring offensive.
The three policemen were killed when a remote-control bomb hit their truck on a main road outside the southeastern town of Khost, said provincial police chief Mohammad Ayoub.
Three policemen, including a senior officer, were wounded, he said.
Earlier, two British soldiers from a NATO-led peacekeeping force were among three people wounded in suicide car-bomb attack in Lashkar Gah, the provincial capital of the southern province of Helmand.
A suicide bomber rammed his car into a vehicle near the entrance of a base used by foreign troops, said senior provincial official Mahaiuddin, who uses one name. The bomber was killed, he said.
A spokeswoman for Britain's defence ministry said three people had suffered non-life-threatening wounds in the blast. Two of them were British soldiers, she said. A suicide car-bomb attack wounded three Americans in Lashkar Gah last week and three British soldiers were wounded in a roadside bomb blast in Helmand on Monday.
The Taliban have been fighting since their ouster in late 2001 to force foreign troops out of the country and overthrow the Western-backed government.
