Gunmen killed an Iraqi intelligence officer in the Shiite holy city of Karbala, one of several deadly shootings targeting security forces on Sunday.

The officer was gunned down after his car was intercepted in the center of Karbala, 50 miles south of Baghdad, health official Salim al-Abadi said.

Gunmen also opened fire on a foot patrol in eastern Baghdad, killing a policeman, police said. Another policeman was killed in a drive-by shooting in the northern city of Kirkuk.

A funeral was held Sunday for a former senior Baath Party official and his 5-year-old granddaughter. Both were gunned down Saturday night while driving in the Baghdad neighborhood of Dora, police said.

A mortar round hit a home in another area in Dora, wounding three children.

In other violence Saturday, gunmen on a motorcycle shot to death two men who were security officers during Saddam Hussein's regime as they were walking in separate locations of Karbala, police said.
