A suicide bomber killed at least 39 people inside a Shi’ite mosque in the Afghan capital Kabul on Friday night, a security official said, and a separate bombing killed at least another 20 at a mosque in the middle of the country.
Early on Saturday morning ISIS claimed responsibility for the attack in the Kabul's western Dasht-e-Barchi district.
ISIS said in the statement that a suicide bomber had detonated a vest. It did not provide evidence to support its claim.
The attack occurred at Imam Zaman mosque in the western Dasht-e-Barchi part of Kabul as worshippers gathered for prayers.
A separate attack on a mosque in the central province of Ghor was also reported on Friday.
Iqbal Nezami, a spokesman for the Ghor provincial police, said at least 20 people were killed in the bombing that appeared to target a local leader.
The targeted official was a top local political and military leader of the Jamiat political party in Ghor, and was killed along with as many as 30 other worshippers, according to a statement from Balkh provincial governor Atta Mohammad Noor, a leading figure in Jamiat.
