A bomber has set off his explosives at a Shia mosque in the Afghan capital, Kabul, and other assailants have stormed the building, killing at least 20 people.
The Daesh Takfiri terrorist group claimed responsibility for the attack that took place when many Muslim worshipers had gathered at the mosque for Friday prayers.
Mohammad Salim Rasouli, chief of Kabul's hospitals, said at least 50 other people, including many children, were injured.
An official at Afghanistan’s Interior Ministry earlier said at least eight policemen had been wounded.
The ministry confirmed that the incident was a "terrorist attack,” with deputy spokesman Najib Danish saying that the bomber had detonated himself while two or three other militants had entered the mosque and were exchanging fire with policemen.
