Multiple attacks in southern Afghanistan killed six militants and left seven coalition troops and an Afghan soldier wounded, the military said on Saturday.
Heavy fighting broke out on Friday night in southern Zabul province's Shahjoy district after coalition forces came under attack by small arms and rocket-propelled grenades, said coalition spokeswoman Capt. Julie Roberge.
Five coalition soldiers were wounded, Roberge said, declining to disclose their nationalities. A suspected Taliban militant was killed, she said.
In neighbouring Kandahar province's Panjwayi district, coalition forces fought off attackers in different locations, killing an estimated five Taliban militants and wounding one, Roberge said.
Four other suspected Taliban insurgents were detained, she said.
Two coalition soldiers and an Afghan soldier were also wounded in the fighting, she said.
More than 10,00 Afghan and coalition troops are deployed across southern Afghanistan in a major military campaign meant to crush resurgent Taliban forces.
Also yesterday night, police in southern Kandahar city raided several Islamic religious schools, known as madrassas, rounding up 125 students to check whether any of them were Taliban fighters in hiding, said Police Chief Azizullah Wardak.
About 100 students have been released after they provided identification cards stating where they were from, he said.
