Iraqis have begun voting in their second full parliamentary elections since the 2003 US-led invasion against a backdrop of deadly attacks. Around 19 million eligible voters will choose from over 6,000 candidates from 86 political groups looking to gain seats in the 325-member assembly. But as polls opened on Sunday, at least 24 people were killed and 60 others wounded. Blasts killed at least 24 people and wounded dozens in Baghdad as Iraqis voted on Sunday in a general election that Al-Qaeda threatened to sabotage, an interior ministry official said. Sixteen people died when two buildings in the capital were blown up in what appeared to be dynamite attacks that wounded a further 16, officials said. Four people were killed by mortar attacks in Baghdad and four more in bomb attacks that between them wounded 40, security officials said. Roadside bombs wounded two in the capital and three near Tikrit, the hometown of the ousted dictator Saddam Hussein, officials said. Other Iraqi cities across Iraq were hit by mortar attacks and bombs but there were no immediate reports of casualties.
