KABUL, Afghanistan (CNN) -- Eight civilians were killed and at least eight others were wounded Wednesday when a roadside bomb struck a mini-bus in eastern Afghanistan, the NATO command said.
International Security Assistance Force (ISAF) troops provided medical assistance at the scene in the Bak District of Khost province.
"This is another example of the insurgents causing the deaths of innocent Afghans," said Richard Blanchette, spokesman for ISAF.
"Our thoughts go out to the wounded and our condolences to the families and friends of those killed in this callous attack on innocent people."
Five of the wounded were brought to an ISAF base nearby and others were taken to a civilian hospital in Khost.
In neighboring Paktika province of Afghanistan, ISAF said an aircraft operated and owned by an ISAF contractor on Wednesday made a hard landing because of "mechanical malfunctions." People on the aircraft suffered minor injuries in the landing, at an aircraft base.
There were no reports of enemy fire.
Both the Khost and Paktika provinces border Pakistan.
