ISIS says it carried out the suicide bomb attack Monday in the Afghan capital of Kabul which killed at least 30 people and left more than 70 injured, reports CNN.

The explosion occurred when the bomber detonated their vest inside a mosque in the sixth police district of Kabul, according to Basir Mujahid, spokesman for the local police force.

Mujahid told CNN that children and women were among the victims.

ISIS claimed responsibility via a statement published by its media wing, Amaq news agency.

The statement said that it targeted the Shia gathering in Kabul but did not disclose any information on the identity of the suicide bomber.

The attack took place at 12:10 p.m. after a suicide attacker entered Shia mosque Baqir ul-Uloom as religious worshipers gathered to mark the Shia ceremony of Arbaeen, which comes 40 days after the major festival of Ashura.

Ashura commemorates the martyrdom of Hussein, the grandson of the Prophet Muhammad who was killed in the year 680 AD.

Taliban spokesman Zabiullah Mujahid has denied the group is responsible for Monday's attack.
