RamaDan

BAGHDAD, Iraq (CNN) -- Several bombings across Baghdad killed 34 people Sunday -- the bloodiest day in the capital during this holy month of Ramadan, an Interior Ministry official said.

A roadside bomb exploded near an Iraqi army patrol near a restaurant in western Baghdad's al-Mansour district.

Also Sunday, in Iraq's Diyala province, at least four people were killed and 17 others wounded in several attacks, a security official in the province said.

The attacks came as Iraqis prepared for Eid al-Fitr, which marks the end of Ramadan with feasts and celebrations. The holiday in Iraq begins Tuesday.

In Baghdad's central Karrada district, a suicide bomber wearing an explosives vest detonated minutes after a bomb in a parked car exploded, the Interior Ministry's head of Explosives and Ordnance Disposal unit said, speaking on state-run al-Iraqia television.

Twenty people were killed and 72 wounded in those attacks, which occurred in a busy commercial area in Karrada. Three women and four policemen were among the dead, and the wounded included seven policemen and women and children, the Interior Ministry said.
