Bombs, shootings kill at least 47 across Iraq: police BAQUBA, Iraq (Reuters) - 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 two years of civil war in neighboring 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. 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. 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. The attack wounded nine others in central Baquba, police said.
