There has been a resurgence of violence in Iraq in recent days, after a lull that followed the December 15 elections.
Political wrangling continues, meanwhile, over allegations of voting fraud in the December 15 parliamentary elections.

Minority Sunni and secular parties accuse the largely Shi'ite Islamic United Iraqi Alliance coalition of intimidating voters and stuffing ballot boxes in the December 15 election.
