KABUL, Oct. 20 (Xinhua) -- A suicide bomb explosion ripped through a mosque in the western side of Afghanistan's capital Kabul on Friday evening, causing casualties, witnesses said.
The blast occurred when dozens of worshippers were offering evening prayers at about 5:40 p.m. local time in a Shiite mosque named Imam-e-Zaman in Dasht-e-Barchi locality, Police District 13 of the city, witness Mohammad Eisapur told Xinhua.
"We found a terrorist entered the mosque building and detonated his explosive jacket among the crowd. The blast caused panic among the worshippers and passers-by as well," he said.
Security forces have cordoned off the area for precautionary measures.
The casualties were shifted to nearby hospitals by ambulances and police vehicles, another witness Sayyed Rahmat told Xinhua by phone.
No group has claimed responsibility yet for the attack, but the Islamic State (IS) terrorist group has routinely claimed responsibility for such attacks.
The IS has attacked several Shiite mosques in Kabul and western Herat province since the beginning of this year.
