The U.S. military says the death toll from Thursday's suicide bomb attack on a Shi'ite funeral in the northern city of Mosul has risen to 50.

More than 80 other people were injured in the blast, many critically. No group has claimed responsibility for the attack.

Friday, grieving families buried their dead in private, canceling plans for a mass funeral procession because of fears it would be attacked.

On the political front, Iraq's main Shi'ite alliance, which swept the January 30 elections, is finalizing a deal with Kurdish leaders to form a coalition ahead of the new parliament's first session next Wednesday.

And a Polish newspaper quoted Warsaw's defense minister Jerzy Szmajdzinski, as saying Poland will withdraw several hundred of its troops from Iraq in July.
