A wave of attacks in Baghdad and northern Iraq killed at least 29 people Wednesday, the deadliest violence to take place this year in a country increasingly divided along sectarian lines.
A suicide bomber killed at least 15 people and wounded more than 100 by detonating a vehicle packed with explosives outside the offices of the Kurdistan Democratic Party in Kirkuk. A separate bomb exploded nearby.
The northern city is at the center of a territorial dispute between Baghdad and the country's autonomous Kurdistan regional government. Another three people died in a separate bombing outside a rival Kurdish political party office in the town of Tuz Khurmato.
In Baghdad, at least three separate attacks left six people dead, while bombings in Baiji, Hawija and Tikrit killed three more and wounded seven others.
There was no immediate claim of responsibility for the bombings, which took place as hundreds of mourners gathered in the western city of Fallajah for the funeral of Sunni lawmaker Ifan Saadoun al-Essawi, who was killed Tuesday by a suicide bombing.
Al-Essawi, a member of the Sunni-backed Iraqiya bloc, was a key founder of a group of Sunni tribal militias who joined forces with the U.S. military to fight al-Qaida in 2006.
