On August 1, 2017, a Shaia mosque in Herat, Afghanistan, was attacked, killing 33 people and injuring 66 others. Two guys carried out the attack, one carrying a suicide vest and the other armed with a rifle. They entered the "Jawadia" mosque during an evening prayer session where approximately 300 people had gathered to worship. The first attacker flung bombs into the crowd before detonating their vests. The second attacker also discharged his rifle into the crowd before blowing himself up. The Islamic State of Khorasan Province (ISKP) claimed responsibility for the attack.
