At least 20 people died, most of them members of the security forces, and 44 were wounded in attacks around Iraq, police told Efe on Wednesday.
A suicide bomber dressed as a soldier blew himself up at the farm of a leader of the Salvation Councils, pro-government Sunni tribal militia, in Tarmiya, 40 kilometers (25 miles) north of Baghdad.
Just minutes later, a second terrorist detonated another bomb at the same location, where a dinner was being held for soldiers and police.
An army colonel, seven of his bodyguards, three police officers and three Salvation Council militia members, including the owner of the farm, died in the double-bombing, and 14 people were wounded.
Meanwhile, at least six people died, including three police officers, and 20 were wounded when a truck bomb driven by a suicide attacker exploded after police opened fire on it to prevent the driver from crashing it into the police station in the village of Al Maula, in the northern province of Nineveh.
Terrorism and religious violence have increased in Iraq in recent months, the bloodiest period in the last five years in the Middle Eastern country, with frequent attacks being staged against security forces, the army and against the Shi'ite community. EFE
