At least 19 people died and 41 were wounded Tuesday in the bombing of a market in the eastern Iraqi province of Diyala.
Many of the injured were badly hurt and the death toll could rise, a member of the Diyala police told Efe.
The two consecutive bomb blasts caused significant material damage to shops in the market and vehicles parked nearby.
The attack took place in the same province where on Monday 25 civilians died and more than 30 were wounded in an attack on a group of Kurds.
That attack was carried out by a suicide bomber who detonated the explosive belt he was wearing in the midst of a group of civilians gathered outside the local Patriotic Union of Kurdistan office.
Also on Tuesday, at least 26 members of the security forces died and 90 were wounded in attacks on different polling places as police and soldiers took part in early voting for the legislative elections.
Almost 20.5 million Iraqis are registered to vote in the elections on Wednesday to choose lawmakers to occupy the 328 seats in parliament. EFE
The Shi'ite Rule of Law coalition headed by current Prime Minister Nouri al Maliki is the favorite to win the balloting. EFE
