At least 22 people have been killed in a series of bombs in busy coffee shops and at other targets across Iraq.

In north and south Baghdad, two blasts tore through cafes where scores of young men had gathered to watch a televised football match, killing eight people.

Two other explosions killed ten people in coffee shops in the city of Baquba, about 50km northeast of Baghdad.

Four more people were killed in bomb blasts in the towns of Jbela and Iskandariya, both south of the capital.

Violence has grown in Iraq since the start of the year, claiming more than 1,000 people in May alone, making it the deadliest month since the sectarian bloodletting of 2006-07.

The latest bombs struck as Iraqis celebrated moves by the UN Security Council towards ending sanctions imposed on Baghdad more than two decades ago after former president Saddam Hussein invaded Kuwait in 1990.
