Death toll has risen to 25 in a suicide attack in Al Sadeq Mosque in Sawaber district of Kuwait during Friday pray ceremonies. The mosque is known to be predominantly visited by Shiite worshippers.
Other 202 people were injured in the attack when a suicide bomber blew himself up inside the mosque.
The ISIS claimed responsibility for the brutal attack via social media.
The statement identified the bomber as Abu Suleiman al Muwahed and said the target was a "temple of the rejectionists," a term used by ISIS to refer to Shiite Muslims.
The mosque contained around 2,000 worshippers, who were kneeling in prayer when a loud explosion occurred, damaging the walls and ceiling.
Kuwaiti parliamentarian Khalil al Salih said "A suicide bomber who looked to be under 30 years of age caused the explosion.’’
He added that he saw several bodies covered in blood on the floor.
Various Twitter accounts claim Kuwaiti Emir Sabah al Ahmad had visited the mosque, with photos depicting him entering a black vehicle.
This is not the first time a Shia mosque was targeted in the Gulf region, two mosques were bombed in Saudi Arabia in May, which killed and injured dozens.
