A suicide bomber killed at least 30 people and wounded 70 others inside the Baqir-ul-Olum Shia mosque in Kabul.  According to Reuters, the suicide bomber entered the mosque as “worshipers gathered for Arbaeen, a Shi’ite ritual marking the end of a 40-day mourning period for the 7th century death of Imam Hussein, grandson of the Prophet Mohammad.” Islamic State claimed responsibility for the attack.

The New York Times quoted Abdullah Abdullah, the chief executive of the Afghan government. He condemned the attack as “a sign of barbarism and cruelty.”
