At least six people were killed and six more wounded in a suicide blast outside a military academy in the Afghan capital on Thursday, an official said, reports Gulf Today
The attack outside the Marshal Fahim National Defense University in western Kabul took place at the road entrance to the war college.
Kabul police spokesman Firdaws Faramarz said the suicide bomber had been on foot. He blew himself up when a soldier challenged him.
"Based on initial information, six people killed, six wounded, police have reached the scene," Faramarz said.
The attacker "detonated himself before reaching his target", Faramarz added, without providing further details.
The attack happened around noon (0730 GMT), a time when students typically leave school early during the month of Ramadan.
No group immediately claimed responsibility.
