Three loud explosions shook central Baghdad in quick succession Sunday, killing at least 12 people. One of the blasts struck near the Iranian Embassy, said Maj. Gen. Qassim al-Moussawi, a spokesman for the city's operations command center. The other two were in western Baghdad. At least 12 people were killed and 42 were injured in the explosion outside the embassy, which was believed to have been caused by an explosives-packed car driven by a suicide attacker, according to two police officers and a hospital doctor. They said many of the victims were employees at a nearby state-run bank. Iran's ambassador to Iraq, Hasan Kazemi Qomi, said it was unclear whether the blast was targeting the embassy itself.
