KABUL: A bomb exploded on Friday inside a
killing at least four people, including the prayer leader, and wounding eight others, an Afghan government official said.
Interior ministry spokesman Tariq Arian said a bomb had been placed inside the mosque but had no additional details. Police cordoned off the area and helped move the wounded to ambulances and nearby hospitals.
No one took immediate responsibility but a mosque attack earlier this month was claimed by the Islamic State group affiliate.
Mofleh Frotan was among the city's more prominent prayer leaders.
Violence has spiked in recent weeks in
with most of the attacks claimed by the
affiliate, headquartered in eastern Afghanistan's Nangarhar province. Earlier this month, IS planted explosives at a mosque in Kabul's posh Wazir Akbar Khan neighborhood, killing the prayer leader and wounding eight others.
The United States blamed the IS affiliate for a horrific attack last month on a maternity hospital in the capital that killed 24 people, including two infants and several new mothers. The hospital was located in the city's Shiite dominated area of Dasht-e-Barchi.
The IS group, which reviles Shiites as heretics, has declared war on the country's minority Shiite Muslims, but has also attacked Sunni Muslim mosques. The mosque targeted Friday is Sunni.
The IS affiliate also took responsibility for an attack on a bus carrying journalists in Kabul on May 30, killing two. Also it claimed credit for an attack on the funeral of a warlord loyal to the government last month that killed 35 people.
Washington's peace envoy
was in the region earlier this week trying to resuscitate a US peace deal with the
, which is expected to eventually be enlisted in the fight against the IS affiliate.
The peace deal signed in February to allow US and NATO troops to leave Afghanistan includes a commitment by the Taliban to fight terrorism and a vow that Afghanistan would not be used to attack the United States or its allies.
Washington previously said the Taliban have been instrumental - along with Afghanistan's National Security and Defense Forces and US air strikes - in reducing the IS's strength in eastern Afghanistan.
