The fourth car bombing in Iraq in a month killed a police station employee Tuesday, wounded at least 18 other people, and sent a column of thick black smoke rising over the Rasafa police station in western Baghdad.
The attack occurred as Shiite Muslims gathered in Najaf, to mourn the death of Ayatollah Mohammad Baqir al-Hakim, a longtime Iraqi dissident, who was among the 83 people killed in Friday's bombing of the Imam Ali Mosque.
At least 121 people have died in the four assaults, each of which has targeted people cooperating with the U.S.-backed Coalition Provisional Authority: In addition to the bombings at the Baghdad police station and the Najaf mosque, 17 people were killed in the August 7 bombing at the Jordanian embassy. The August 19 attack on the United Nations' Canal Hotel headquarters killed 20 people, including Sergio Vieira de Mello, the U.N.'s top envoy to Iraq.
