Four people, including three policemen, were killed in violence in and around Baghdad on Sunday, police and an interior ministry official said.
In the deadliest attack, a suicide car bomb in the town of Garma, 50 kilometres (30 miles) east of the capital, killed three policemen including a lieutenant colonel, according to Lieutenant Colonel Hatif al-Dulaimi.
The blast, which targeted a police checkpoint in the town, in predominantly Sunni Anbar province, occurred at around 1:00 pm (1000 GMT) and left six others wounded, including three policemen.
Also on Sunday, an employee of Iraq’s anti-corruption watchdog Laith Mohaned was shot dead by unknown gunmen along the airport road, an interior ministry official said.
The official added that a roadside bomb at a petrol station at Saadun street in central Baghdad Sunday morning wounded five people, while two bomb attacks in eastern and western districts of the capital injured six others.
Two mortars were also fired into Baghdad’s heavily-fortified Green Zone, which is home to several foreign embassies and government buildings.
No casualties were immediately reported.
Violence appears to have risen again across Iraq in recent months, with July and August recording two of the highest monthly death tolls since 2008, according to government figures.
