Afghan officials say an accidental explosion killed four insurgents and a civilian near a sporting event in an area controlled by the Taliban, the Associated Press (AP) reported.
Maj. Hanif Rezaie, an army spokesman, said one of the militants killed in the northern Baghlan province was a local commander.
Another 20 people, including Taliban militants and civilians who had gathered to watch a volleyball match, were wounded, according to provincial official.
According to AP, the official spoke on condition of anonymity because he was not authorized to speak to the media.
Elsewhere in Afghanistan, a female university student was killed when a sticky bomb attached to a vehicle was detonated, according to the office of the provincial governor of Nangarhar province.
