Kuwait: Kuwait has arrested two police officers as part of a security crackdown on Islamist militants launched after last week’s deadly bombing on a mosque claimed by Daesh, newspapers reported on Wednesday.

The attack by a suicide bomber on Friday killed 27 people and injured more than 200, prompting the government to declare it was at war with Islamist militants would strike out at cells believed to be on its soil.

Security forces found weapons, ammunition, maps and slogans supporting Daesh in a raid on the home of a student and another suspect who said they had received the weapons from the officers, the Al Rai daily quoted security sources saying.

About 90 people have been detained by authorities investigating the attack on a Shiite mosque in Kuwait City, the Al Qabas newspaper said on Wednesday, up from 60 reported by media on the previous day.

The Kuwaiti interior ministry was not immediately available for comment.

Ten suspects — among them Saudis, Kuwaitis and stateless residents — had been referred to the public prosecution, it reported, a move that indicates a criminal case has been opened.

Among the ten are five principal suspects accused of helping the suicide bomber, a Saudi, carry out the attack, it said.

Kuwaiti officials have said the attack was aimed at stirring up sectarian strife in the country, where Sunnis and Shiites have traditionally coexisted in peace.

Kuwait’s interior minister, Shaikh Mohammad Al Khalid Al Sabah, said on Tuesday security forces were determined to dismantle any further cells before these were able to strike.

Friday’s attack was one of three that day on three continents linked to Islamist militants. In France, a man was arrested on suspicion of beheading his boss and trying to blow up an industrial gas plant, while in Tunisia a gunman shot nearly 40 people at a beach resort in Tunisia.
