Hours after a bomb was detonated outside of a U.S. consulate in Jeddah, Saudi Arabia, another explosion hit the holy city of Medina. A suicide bombing was reportedly close to the Prophet’s Mosque, one of Islam’s holiest sites and the burial place of the Prophet Muhammad. At least four people were killed in the Medina explosion. Footage circulating on social media showed a vehicle on fire in what appeared to be a parking lot. Another explosion also hit the eastern city of Qatif, local media reported. Witnesses said at least one suicide bomber may have targeted a Shia mosque.
