Baghdad, Nov 2 (DPA) More than 30 people have been killed in Iraq from a series of car bombings, suicide bombings and explosions from improvised devices that rocked various parts of Baghdad Tuesday evening, according to security sources and witnesses.

Witnesses said that more than 70 others were injured in the attacks that targeted cafes, restaurants and popular markets.

There were around 11 car bombings and attacks by suicide bombers, according to witnesses who spoke to DPA.

Police rushed to close all roads leading to the sites of the explosions as the sound of ambulances wailed throughout the city.

Earlier Tuesday, five people had been killed and two injured in unrelated attacks, security sources said.

Three policemen and an Al Qaeda militant were killed by a bomb targeting a police convoy in the area of al-Khaneqeen, 60 km north-east of Baghdad. Two policemen were injured in the blast.

The convoy had been transporting Emad Rawkan, an Al Qaeda leader in the al-Saadiya area, to the village of al-Hafayif to investigate his involvement in a bomb attack that left four policemen dead last week.

In a separate incident, a man was killed by a bomb that had been placed outside his home in the city of Fallujah, 60 kim west of Baghdad.

The latest round of attacks comes just two days after militants reportedly affiliated with Al Qaeda took worshippers hostage at a church in Baghdad. More than 52 people were killed and more than 75 injured in the incident.

A day earlier, more than 30 people had been killed and more than 67 injured when a suicide bomb ripped through a crowded coffee shop in the Iraqi city of Baquba, some 57 km north of Baghdad.

The attacks come amid a political stalemate surrounding the formation of a new government that has dragged on for nearly eight months.
