Violence in Iraq has reportedly killed more than 30 people in 24 hours.
The bloodshed comes as officials count ballots from the April 30 general election, the first since U.S. troops withdrew in late 2011.
Three people were killed in Baghdad and the northern city of Mosul on May 4.
In Fallujah, west of Baghdad, shelling in southern areas of the city killed at least five people.
It was not immediately clear who was behind the bombardment, which began on May 3.
North of Baghdad, 11 people were killed on May 3 in an attack on a bus carrying Shi'ite pilgrims.
Also on May 3, police found the bodies of eight family members shot dead southeast of Baghdad.
Iraq is experiencing its worst violence since sectarian Sunni-Shi'ite fighting killed tens of thousands in 2006 and 2007.
