Gunmen have stormed Kabul University ahead of the opening of an Iranian book fair, wounding at least six people, government officials say.
Interior ministry spokesman Tariq Arian said several gunmen had entered the campus, sending students fleeing.
He said security forces had blocked the campus and fired back at the gunmen.
The Taliban denied involvement in the attack. Afghan education centres have often been targeted by militants in recent years.
“We don’t know whether we are dealing with a coordinated attack or something else,” Mr Arian said.
Hamid Obaidi, a spokesman for the ministry of higher education, told the AFP news agency that the attack began when government officials were expected to arrive for the opening of the fair. (BBC)
