A bomb attack, claimed by the Takfiri ISIL terrorist group, has targeted another Shia mosque in Saudi Arabia’s Eastern Province, with a confirmed death toll of four as of now.

The Saudi Interior Ministry said the attack took place on Friday close to Imam Hussein (PBUH) Mosque in the provincial capital of Dammam, located about  400 kilometers (250 miles) east of the capital, Riyadh.

Saudi media quoted an Interior Ministry spokesman as saying that a bomber, who was dressed in women’s clothing, detonated his bomb in the parking lot of the mosque after his car was stopped by security guards. 

Four people have so far been confirmed killed in the bomb attack, according to the Saudi Interior Ministry. It was not immediately clear if the bomber was among the four victims.

The new assault came a week after a bombing hit a mosque in the al-Qudaih village in the province’s Qatif district, killing 21 worshipers, including two children.

The Takfiri ISIL terrorist group claimed responsibility for the May 22 attack.
