A roadside bomb killed three soldiers from the American-led coalition, the U.S. military said Thursday.
An American military statement gave no details of the nationality or the precise location of the attack in western Afghanistan, but said a fourth soldier was wounded.
The governor of Farah province in western Afghanistan, Ruhul Amin, said Thursday that a roadside bomb hit a vehicle carrying three coalition members on patrol at night, but he did not specify their nationality or indicate that there had been fatalities.
U.S. forces in Farah province run a reconstruction team.
The bombing came a day after the U.S.-led coalition said an airstrike by its forces in Khost province may have been a case of mutually mistaken identity. Afghan officials said nine Afghan soldiers died in the airstrike. The coalition did not give a death toll or identify the nationality of the force responsible for the strike.
Airstrike kills 10 in Pakistan
At least 10 people were killed and six others injured in a suspected U.S. missile strike Thursday in Pakistan's restive tribal region, Pakistani intelligence officials and a witness said. The attack apparently targeted a madrassa, or religious school, operated by Taliban commander Sirajuddin Haqqani in North Waziristan, an area known to be a haven for al-Qaida and Taliban insurgents. Officials said reports from the scene suggested that all those killed in the attack were local Pakistanis, not foreign fighters.
