Iraqi officials say at least 20 people have been killed in two suicide bomb attacks in the capital, Baghdad.
In one attack, suicide car bomber set off his explosives at the entrance of a busy market Sunday in a mainly Shi'ite district. At least 13 people were killed in the blast that was claimed by Islamic State.
A separate suicide blast in Baghdad killed at least seven people.
IS has claimed responsibility for a series of bombings in the Baghdad area over the past week, killing dozens of people. At least 30 people were killed in a suicide blast in Sadr City last week.
The attacks come as Iraqi forces are engaged in a massive military operation aimed at driving Islamic State from the northern city of Mosul.
More than 125,000 Iraqis have been displaced since the Mosul offensive began in October, according to the United Nations.
The Pentagon estimates there are still 3,000 to 5,000 IS fighters in Mosul.
