At least ten Iraqi policemen and soldiers have been killed in a series of attacks north of Baghdad. In the capital, at least four people died and 17 others were wounded by five explosions in quick succession. Car bombs were responsible for at least four of the blasts.
In the second major assault on Iraqi security forces in three days, gunmen stormed a police checkpoint near an Interior Ministry commando base north of Baghdad.
Police say up to six insurgents died in the ensuing clashes that lasted several hours.
There was a lull during elections two weeks ago, partly due to an informal truce by some Sunni Arab insurgent groups, but violence has since surged.
Thousands of Sunnis have taken to the streets in recent days, crying foul over the outcome and demanding fresh elections or a recount.
The results show the incumbent Shi’ite Islamic bloc in a strong lead in crucial areas like Baghdad, despite a large turnout by Sunnis who had boycotted a previous vote.
Final results will not be known until January.
