Dozens killed in latest Baghdad bombs

A spate of bombings Wednesday in mainly Shia neighborhoods of the Iraqi capital Baghdad killed at least 28 people and wounded 65, security and medical officials said.

The series of blasts struck across Baghdad from around 7:30 a.m. local time, according to the officials who spoke on condition of anonymity.

The bombings lasted for about an hour, targeting crowded markets. 

Police officials said the deadliest attack was in the central Sadria neighborhood, where a parked car bomb went off at an outdoor market, killing five shoppers and wounding 15.

Other attacks took place in Shaab, Tobchi, Karrada, Azamiyah and Amil neighborhoods. 

Al Jazeera's Imran Khan, reporting from Baghdad, said the death toll could have been higher as the attacks happened on a day that has been declared a holiday by the government due to heavy rains.

There was no immediate reaction from the Iraqi government. 

Iraq is experiencing a surge in violence since April, following a deadly security raid on a Sunni protest camp in the country's north. Since then, more than 5,500 people have been killed, according to the United Nations.
