Two gunmen and a suicide bomber killed at least four people and wounded eight more in an attack at a mosque in the Afghan capital of Kabul, the Interior Ministry says.
The three suspected attackers tried to enter the Al Zahra mosque, used by Kabul's Shi'ite minority, on Thursday but were blocked by police, setting off a gun battle, ministry spokesman Najib Danish said.
The attackers then took refuge in a kitchen, where one detonated a bomb while the other two were killed by security forces, he said.
The attack, which has been claimed by Islamic State, came as mosques around the city were crowded for a night of religious observances as part of the Islamic holy month of Ramadan.
Kabul's Shi'ite minority have been targeted by suicide bombings in the past. An attack on a Shi'ite mosque in November killed more than 30 people.
Islamic State militants claimed responsibility for that attack, as well as an attack last July that killed more than 80 people at a mostly Shi'ite demonstration.
