More than 60 Iraqis have been killed after bomb attacks in a busy market and outside a town hall in the mostly Shia Baghdad district of Sadr City.
It is the first day of the work week in Iraq and the market was packed with shoppers.
Police said a suicide bomber drove a vehicle packed with explosives into the entrance of the market.
Earlier, in the northern city of Kirkuk, at least 20 people were killed when a car bomb exploded.
Police said more than 50 others were injured, 30 of them seriously.
