ISIS Vows More Attacks on Saudi Mosques for Allying With the USA

(CAIRO)—The Islamic State of Iraq and Greater Syria (ISIS) has released an audio recording purporting to feature the suicide bomber who killed 15 people at a police compound mosque in Saudi Arabia.

The audio, along with a photo of the suicide bomber identified as Abu Sinan al-Najdi, was posted late Friday on ISIS-affiliated Twitter accounts.

The speaker on the recording vowed more attacks, saying Saudi rulers and troops “will not enjoy peace” for taking part in the U.S.-led coalition battling ISIS in Iraq and Syria. He urged other militants to carry out suicide bombings, saying explosive belts are more effective than firearms.

The attack in Abha on Thursday was one of the deadliest against Saudi Arabia’s security personnel in years. Most of the victims were members and recruits of the kingdom’s special forces.
