Officials have identified the man allegedly responsible for detonating a bomb near a U.S. consulate in Jeddah—the first of three deadly attacks that rattled the kingdom Monday. The suicide-bomber who perished in that attack was 34-year-old Abdullah Qalzar Khan, who lived in the area with his wife and her parents, several sources reported. Saudi Arabian authorities also identified a suicide bomber who struck outside the Prophet’s Mosque in Medina, one of Islam’s holiest sites, as a Pakistani man who reportedly arrived just 12 hours before to work as a driver. He was not named by officials. A third bombing hit near a Shiite mosque in the city of Qatif at around the same time. No group has claimed responsibility for any of the three attacks on Saudi Arabia, which all took place within the same 24 hours.
