Suicide bombers blew themselves up in Qatif and Medina after sundown on Monday, several hours after Saudi security officers foiled an attack near the US Consulate in Jeddah.
In Medina, a bomb exploded in the vicinity of a police post outside the Prophet’s Mosque, killing four policemen and two civilians, reports said.
A police source told Arab News that the officers manning the post were having their iftar meal when the suicide bomber struck.
A video circulated on social media showed a car burning and at least two security officers were seen lying on the open ground and two others lay crumpled near a burning car.
In Qatif, a governorate in the Eastern Province, two suicide bombers blew themselves up one after the other outside the Faraj al-Omran Mosque. No casualties were reported.
The number of fatalities reported does not include the three suicide bombers.
Earlier Monday at 2:15 a.m., a suicide bomber blew himself up near the US Consulate when security officers confronted him as he moved suspiciously at a parking lot of the Dr. Soliman Fakeeh Hospital.
