Seven people were killed Thursday in attacks in northern and central Iraq, police said, dpa reported.

In Dujail, some 65 kilometres north of the capital Baghdad, one man was killed and seven injured when an explosion hit a vehicle transporting farm workers.
Two members of the pro-government Sunni Sahwa militia were killed in nearby Yathrib when insurgents attacked their checkpoint. One of the gunmen was also killed.
Iraq has witnessed near-daily attacks since US troops withdrew in December 2011, raising fears of a return to the sectarian tensions that drove the country close to civil war in 2006 and 2007.
The recent spike in violence comes amid a widening crisis between the Shiite-led government and the country's formerly dominant Sunni minority.
Thousands of Sunni protesters have been rallying for nearly two months against Shiite Prime Minister Nuri al-Maliki, demanding a repeal of laws they claim target Sunnis.
