Afghan officials say a suicide bomber has killed at least 10 people, including two police officers, at a market in the south of the country.
The governor of Nimroz province, Ghulam Dastagir Azad, says the bomber was apparently targeting one of the police officers who was killed in Friday's blast in the town of Zaranj.
Also Friday, the U.S. military said coalition forces killed five militants in a Thursday attack on a bomb-making network in the southern province of Zabul.
Officials said troops came under fire while pursuing a Taliban militant known to have directed roadside bomb attacks along the country's major highway.
Also Thursday, the U.S. military says a suicide car bomber killed two U.S. soldiers in the southern province of Kandahar. Local officials say the blast also killed two Afghan civilians and wounded 21 others.
