BAGHDAD — Suicide attacks, bombings and shootings erupted across Iraq Wednesday, killing at least 17, officials said, the latest in a surge of attacks that has raised concerns about all-out sectarian fighting.
The deadliest attack was in Baghdad's southeastern suburb of Nahrawan, where a roadside bomb went off in a busy street, killing at least seven civilians and wounding 15, a police officer said.
In the southeastern Zafaraniyah neighborhood, the bodies of three workers were found inside a house under construction, another police officer said. All were shot in the head at close range.
In the northern city of Mosul, two suicide attackers rammed their explosives-laden cars into two military barricades, killing four soldiers and one civilian, another police officer said. Another 23 people were wounded. Mosul is 360 kilometers (220 miles) northwest of Baghdad.
Also Wednesday, two anti-al-Qaida Sunni fighters were killed and six wounded when a roadside bomb hit their car in the western Baghdad suburb of Abu Ghraib, police said. The pro-government group called Awakening Council joined with U.S. troops to fight al-Qaida before the U.S. pullout in late 2011. Since then, its members have been a frequent target for al-Qaida in Iraq, which considers them traitors.
Four medical officials confirmed the casualty figures. All officials spoke on condition of anonymity as they were not authorized to talk to reporters.
Violence increased sharply in April and May, with frequent bombings in civilian areas raising concerns that a widespread sectarian conflict might once again break out in Iraq. According to the United Nations mission to Iraq, last month's violence claimed the lives of 761 Iraqis and wounded 1,771 others.
