A suicide car bomb detonated near an Iraqi National Guards barracks Tuesday in western Baghdad, killing 10 people and injuring 40, police said. The explosion took place in Baghdad's Qadessiyah district.
Meanwhile, gunmen killed the governor of the Baghdad province, Ali al-Haidari, and six of his bodyguards on Tuesday, officials said.
Al-Haidari's three-vehicle convoy was passing through Baghdad's northern neighborhood of Hurriyah when gunmen opened fire, said the chief of his security detail, who asked only to be identified as Maj. Mazen.
"The governor was in his armored BMW and we were in two other cars," said Maj. Mazen, reached on al-Haidari's cell phone. "Our convoy was moving in Hurriyah and they came from different directions and opened fire at us."
Separately, a US marine was killed in action in al-Anbar province west of Baghdad on Tuesday, the US military said.
Elsewhere, three Britons were confirmed dead in a bomb blast in Baghdad on Monday. They died as a car bomb exploded at a US-manned checkpoint to the Green Zone.
Meanwhile, the suicide bomber who killed 22 people when he blew himself up in an American mess hall in the northern Iraqi city of Mosul was a Saudi medical student, an Arabic daily reported Monday.
The London-based Asharq Al-Awsat newspaper identified him as 20-year-old Ahmed Said Ahmed al-Ghamdi, citing unnamed friends of the man's father. The friends said activists of an Iraqi resistance group contacted al-Ghamdi's father to tell him his son was the attacker in Mosul.
