Police in Kuwait say they have interrogated a number of suspects with possible links to the suicide bombing that killed 27 Shiite worshippers during midday Friday prayers.

An Interior Ministry statement on Saturday says that police have also arrested the owner of the car that was used by the suicide bomber to drive to the Shiite mosque, where he detonated his device once inside. Police did not say how many suspects are being interrogated.

An affiliate of the Islamic State group claimed responsibility for the attack, which also wounded more than 200 worshippers.

The government is helping plan a mass funeral on Saturday for those killed. Thousands of Sunnis and Shiites from across the country are expected to take part in the procession and prayer at Kuwait's Grand Mosque.
