Kuwaiti state security have arrested three people suspected of being involved in the bombing of a Shia mosque last Friday that killed 27 people and wounded more than 200, Kuwaiti daily al-Qabas has stated.
The day was declared a day of national mourning and a mass funeral was planned to take place this Saturday.
ISIS claimed responsibility for the attack on early Saturday via social media.
This attack was Kuwait’s worst militant attack in years.
Security forces was able to locate and detain the owner of the vehicle that the suicide bombers used to get to the mosque, but the driver has still not been found.
The bombing was intended to create hostility that could cause potential conflict between Kuwait’s Sunni majority and the Shia minority leading to division in the country, government officials said.
The Shia community in Kuwait make up between 15 to 30 percent of the population.
Both the Sunni majority and Shia minority have lived side by side and seen very little disharmony.
Parliament member Khalil al-Salih was at the scene in the Sawaber district in the eastern part of the Kuwaiti capital .
Al-Salih reported that about 2,000 worshippers were kneeling in prayer when the bomber walked in and detonated his explosives, destroying the mosque and causing numerous fatalities and serious injuries.
He added that he saw several bodies covered in blood on the floor.
Various Twitter accounts claim the Emir of Kuwait Sabah al Ahmad has visited the mosque, with photos depicting him entering a black vehicle.

This is not the first time a Shia mosque has been targeted in the Gulf region in recent months. Two mosques were bombed in Saudi Arabia in May, in attacks which also killed and injured dozens.
