A bomb explosion in the Sadr City area of the Iraqi capital, Baghdad, has killed at least 30 people and injured more than 60, officials say.
The blast targeted labourers who had gathered for work early in the morning in Mudhafa Square, in the densely populated, largely Shia neighbourhood.
At least 50 people have died in other attacks in Iraq.
Meanwhile, the death of two US troops has taken US losses in October to 101 - the highest total since January 2005.
One of the troops, a marine, was killed on Sunday in combat in Anbar province, west of Baghdad, the US military said.
The other, a military policeman, was reportedly killed in eastern Baghdad.
