BAQUBA, Iraq Car bombs, roadside bombs and shootings killed at least 47 people in Iraq on Sunday, police and medical sources said, as tensions intensify between Sunni and Shi'ite Muslims across the Middle East.
Sunni Muslim insurgents and the al Qaeda-affiliated Islamic State of Iraq have significantly increased their attacks this year. More than 1,000 Iraqis were killed in July, the highest monthly death toll since 2008, according to the United Nations.
More than two years of civil war in neighbouring Syria have aggravated deep-rooted sectarian divisions and shaken Iraq's fragile coalition of Shi'ite, Kurdish and Sunni factions.
The renewed violence, eighteen months after the last U.S. troops withdrew from Iraq, has sparked fears of a return to the scale sectarian slaughter in 2006 and 2007.
Iraqis have suffered extreme violence for years, but since the start of 2013 the intensity of attacks on civilians has dramatically increased. Bomb attacks have increasingly targeted cafes and other places where families gather, as well as the usual targets of military facilities and checkpoints.
The biggest of Sunday's attacks took place in central Baquba, 65 km (40 miles) northeast of Baghdad when a car bomb blew up near a housing complex, killing at least 11 people and wounding 34, police said.
Earlier attacks included the killing of five soldiers in Qiyara town, some 290 km (180 miles) north of the Iraqi capital, when suspected militants ambushed two taxis taking soldiers from Baghdad to join their units in Mosul, military sources said.
"One of the cars escaped the ambush but the second one could not and the militants shot dead five soldiers and burned their bodies after they killed them," a senior intelligence military officer, who declined to be named, said.
A medical source at the morgue in Mosul confirmed the soldiers' bodies had been burned.
Police said that seven people were also killed and 30 others were injured in two separate explosions in Madaen, about 30 km (20 miles) southeast of Baghdad.
Another two explosions took place in commercial areas in western and northern Baghdad, killing 12 people and wounding 45, police and medical sources said.
A bomb stuck to a car killed three people and wounded four in eastern Baghdad, police and medical sources said.
Earlier on Sunday, police said three people were killed and 15 wounded when a car bomb exploded in Balad, 80 km (50 miles) north of Baghdad. Two people were shot dead near their homes in eastern Mosul, 390 km (240 miles) north of Baghdad, police said.
Roadside bombs also killed two members of a displaced Shi'ite family who had recently returned to their home. The attack wounded nine others in central Baquba, police said.
No group immediately claimed responsibility for Sunday's attacks but Sunni Islamist militants have been regaining momentum in their insurgency against the Shi'ite-led government in recent months, emboldened by the civil war in Syria.
On Friday, a suicide bomber killed 25 people and wounded more than 50 in Baghdad when he detonated his explosives inside a busy cafe near a park.
