A car bomb has killed at least eight Iraqis and wounded 38 others in northern Baghdad.

The car bomb was detonated by remote control on the side of a road during morning rush hour in Baghdad's al-Qahira district, a largely Shia neighborhood in the north of the city, security sources said.

Witnesses told AP news agency that a minibus with passengers on board had been behind the parked car when it detonated, killing all on board.

A second roadside bomb detonated as soldiers cordoned off the scene of the attack, police said.

At least three Iraqi soldiers were among the dead, hospital sources told AFP news agency.

Emergency extended

Meanwhile, police said they had found the bodies of 19 men across the Iraqi capital, apparently shot in sectarian killings.

Hundreds of Iraqis have been killed by bombings, shootings and mortar and rocket attacks in sectarian violence that has surged this year across Iraq, particularly in the country's capital.

On Tuesday, Iraq's parliament resumed after its summer recess and voted to extend a state of emergency for a month.

The measure, which has been in place for almost two years, covers every area except the autonomous Kurdish region in the north and grants security forces the power to impose curfews and make arrests without warrants.
