The U.S.-led coalition in Afghanistan says two of its soldiers have died in a "hostile incident" in the volatile south.
A coalition statement issued Sunday says one International Security Assistance Force service member was killed and another died of wounds sustained in the incident. No further details were immediately available.
Also Sunday, the U.S.-led coalition said it had killed five suspected militants and detained four others in a raid in the northern province of Kunduz. The coalition said Afghan forces helped carry out the raid.
But some local officials are contesting the report, saying the people killed were civilians working for the district mayor. The report could not be independently confirmed.
Separately, officials say a bomb hit a vehicle in the eastern province of Khost Sunday, killing one person and wounding 11 others.
Civilian deaths caused by coalition activities have been one of the biggest sources of tensions between Afghans and foreign forces in the country.
Afghan President Hamid Karzai has demanded that international forces take greater care to avoid harming civilians in their fight against Taliban and al-Qaida militants.
