Afghan police say two suicide bombers struck a Shi'ite mosque in the western city of Herat, killing at least one person and wounding seven others.
Police spokesman Abdul Ahad Walizada said the suicide bombers tried to enter the Nabi Akram Mosque on March 25, but one was shot dead by security guards and the other blew himself up before reaching the hall where worshippers were praying.
The Islamic State extremist group claimed responsibility for the attack.
The area around the mosque was cordoned off by police and ambulances were seen rushing victims to hospitals in the city.
The Sunni extremists have frequently targeted Afghanistan’s Shi'ite minority, which they view as apostates.
The group claimed responsibility for a suicide attack outside a Shi'ite mosque in Kabul on March 21 that killed 33 people and wounded dozens as people in the capital celebrated Norouz, the Persian new year holiday.
According to the UN Assistance Mission in Afghanistan, 161 people were killed and 257 others were wounded in 2017 in targeted sectarian attacks against Shi'ite places of worship or worshippers.
