Seven defendants have been sentenced to death for the Islamist militant suicide bombing of a mosque in June in Kuwait that killed 27 people.

Eight other suspects were given prison sentences ranging from two to 15 years by a Kuwaiti criminal court while 14 other defendants were acquitted.

Islamic State claimed responsibility for the June 26 bombing, when a Saudi suicide bomber blew himself inside the Imam al-Sadeq mosque in Kuwait City.

Hundreds of Shi'ite Muslims were performing Friday noon prayers when the bomb went off.

Kuwait cracked down on Islamist militants after the bombing, the country's worst militant attack. Officials say the bombing was aimed at stoking strife between Sunnis and Shi'ites in the majority Sunni state, where the two sects have usually co-existed in peace.
