BAGHDAD — Bombings in Iraq killed five people and wounded 34 others on Sunday, security and medical officials said, after a bloody week that cost the lives of more than 100 people.

A car bomb targeting an army patrol killed one soldier and wounded three others in Fallujah, west of Baghdad, army Lieutenant Colonel Mohammed al-Obaidi from the Anbar Operations Command said.

A roadside bomb in Fallujah also killed a child and wounded three other people, Obaidi said.

Doctor Assem al-Hadithi of Fallujah General Hospital confirmed the facility had received the bodies of the soldier and the child.

In Al-Sharqat, 290 kilometres (180 miles) northwest of Baghdad, a car bomb that exploded near a police station among a line of cars waiting for petrol killed two people and wounded 26, a police colonel said.

And a roadside bomb north of Kirkuk, a city in north Iraq, killed Murad Mohammed, an Iraqi employee of a Turkish security company, and wounded two others, a high-ranking security official said.

The violence comes a day after 32 people were killed and dozens wounded in two car bombs targeting Shiite pilgrims in Baghdad, while 72 people were killed and more than 250 wounded Wednesday in a wave of attacks across Iraq.

Violence has declined dramatically since the 2006-2007 peak of sectarian bloodshed, but attacks remain common, especially in Baghdad. A total of 132 Iraqis were killed in May, official figures show.
