Separate blasts in Afghanistan on Friday 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 defense ministry said three people had suffered non-life-threatening wounds in the blast. Two of them were British soldiers, she said.
A Taliban spokesman said by telephone from an undisclosed location the bomber was a Taliban member.
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.
U.S.-led troops and Afghan soldiers killed two insurgents and captured two during an offensive in the central province of Uruzgan, the U.S. military said on Friday.
The two captured insurgents “were responsible for recruiting suicide bombers to attack Afghan government officials and coalition forces”, it said in a statement.
Separately, Taliban gunmen killed a member of a government-appointed council of Muslim clerics in the southern province of Kandahar as he was walking home from a mosque on Thursday evening, a spokesman for the council said.
Taliban have over the past year killed several clerics who support the government.
