Saudi Arabian security forces on Monday raided homes of several suspected terrorists who reportedly have ties to the Islamic State group. The raid took place in the town of al-Khafji on the Kuwait border. Saudi Arabia state television reported police arrested Faisal Mohammed al-Zahrani, one of the 16 suspects thought to have helped carry out deadly attacks in Shiite mosques in the eastern part of the country earlier this summer. One officer was shot during the raid.

Last month Saudi Arabia announced the names of 16 men linked to the May 29 suicide bombing outside the Al-Anoud Mosque in Dammam, which killed four people, and the May 22 attack at the Imam Ali bin Abi Talib Mosque in Qudayh, which killed 21 people. Al-Zahrani was on that list, but little else is known about him. A suicide bomber detonated his explosive belt at the Al-Anoud mosque in and killed four people. The Islamic State group claimed responsibility for both of the attacks.

The raid in eastern Saudi Arabia comes just over one week after militants affiliated with the Islamic State group, also known as ISIS or ISIL, attacked a Shiite mosque in Kuwait. The raid in eastern Saudi Arabia could point to the government's growing concern that the ISIS threat is growing in the country.
