A series of explosions across Baghdad, the Iraqi capital, has killed at least 63 people and wounded 285 others, hospital and police officials say.
The bombings began at about 6:15pm local time on Tuesday and took place in at least 10 neighbourhoods, involving booby-trapped cars, roadside bombs and mortar strikes.
"Ten cars exploded with bombs inside them. There were also four roadside bombs and two sticky bombs," said Major General Qassim al-Moussawi, a Baghdad security spokesman.
The attacks appeared directed mostly at the city's majority Shia population, though some blasts occurred in Sunni neighborhoods. Rawya Rageh, Al Jazeera's correspondent in Baghdad, said most of the blasts happened near markets and banks and areas that are usually crowded at that time in the evening.
"There have been a series of attacks of a highly sectarian nature recently. The city is witnessing some very violent days," Rageh said.
"It's all being blamed on the failure of Iraqi politicians to agree on the formation of a government.
