At least 17 people were killed in attacks across Iraq on Wednesday, including four in a suicide bombing on a bus in Baghdad Shiite district of Sadr City, a security official said.
The attacks came as a US panel prepared to release a report on how to curb the violence in the war-torn country.
Eight people were killed and 40 others wounded when a series of mortar bombs slammed into a market in central Baghdad's Al-Midan area, the official said.
Four people, including two women, were killed when a suicide bomber blew himself up on a bus travelling through Sadr City. Another 12 were wounded in the attack.
On November 23 a series of car bombings in the Shiite district killed 202 people in by far the biggest attack in Iraq since the 2003 war to topple Saddam Hussein.
In another attack four people were killed when a bomb went off in a shop near a bus station in the town of Iskandiriyah, south of Baghdad, police said.
In western Baghdad's upscale Mansur district gunmen attempted to assassinate Brigadier General Mohsen Qassim, the head of the security force of Iraq's Sunni-controlled ministry of higher education, but only killed his driver.
Sectarian and insurgent violence has continued unabated in Iraq with dozens killed every day.
