At least 10 people were killed on Thursday in two bombings in the Iraqi capital Baghdad, local media reported, citing police, DPA reported.
Police said the death toll was expected it to rise, the reports said.
Iraq has witnessed near-daily attacks since US troops withdrew in December 2011, raising fears of a return to the sectarian tensions that drove the country close to civil war in 2006 and 2007.
The violence comes at at time of a widening crisis between the Shiite-led government and the country's Sunni minority.
Thousands of Sunni protesters have been rallying for more than two months against Shiite Prime Minister Nuri al-Maliki, demanding a repeal of laws they claim target Sunnis.
