Bombings and shooting attacks across Iraq have left 37 people dead, sources in the security forces told Efe Friday.
Ten people died and 20 others were wounded by two bombs in Ramadi, capital of the western province of al-Anbar.
A limpet mine attached to the car of a senior member of the pro-government Sahwa Sunni militias exploded and a second device was detonated after other militiamen and civilians gathered at the scene, the source said.
The Sahwa militias arose in 2006 to battle al-Qaeda elements. Though most Sunnis supported that mission, some within the community have turned against the militias because of their loyalty to Iraq's Shi'ite-led government.
The double-bombing came two days after a Sunni coalition swept to victory in the al-Anbar provincial elections.
A score of people died Thursday night when two bombs went off next to a coffee shop in Baquba, capital of the eastern province of Diyala.
May was Iraq's bloodiest month in more than five years, according to the U.N. mission in Baghdad, which estimated the number of people killed in politically motivated violence at 1,045. EFE
