A suicide bomb and gun attack targeting a mosque in Saudi Arabia's Eastern Province killed at least two people and wounded at least seven others on Friday, the Interior Ministry said.
The Ministry also stated that Saudi authorities prevented the two suicide bombers from entering the mosque during the Friday prayer service.
"When security men stopped them, one blew himself up at the entrance of the mosque and there was an exchange of fire with the other. He was wounded and arrested wearing an explosive belt," the spokesman said.
An activist told Reuters that an explosion was followed by a shooting at the Imam Ridha Mosque in the town of Mahasen in the al Ahsa region of the oil-producing province.
"The explosion happened outside the mosque, at the courtyard of the mosque, while another one entered with a machinegun. There are martyrs and wounded," the witness said.
"The young men grabbed his gun and beat him up, but he did not die. The police then came and took him away and the wounded were taken in private cars because ambulance cars did not arrive quickly."
Videos and photos that circulated social media showed at least three people lying motionless inside the mosque, one with a mutilated hand.
No one has claimed responsibility for the attack, however many of the recent bomb attacks have been claimed by DAESH terrorist group.
