BAGHDAD - A wave of attacks across Iraq killed at least 15 civilians Wednesday as government forces pressed on with their offensive to dislodge Islamic State militants from a major city west of Baghdad, officials said.
No one immediately claimed responsibility for the attacks, though they bore the hallmarks of the Islamic State, a Sunni militant group that has targeted Iraqi forces, civilians and especially Shiites.
In the Shiite-majority town of Khalis, about 80 kilometers (50 miles) north of the Iraqi capital, two explosives-laden cars were detonated. The first car was parked inside a bus station and that explosion killed three and wounded 10, a police officer said.
The second car bomb exploded at the town's outdoor grocery market, killing four civilians and wounding eight.
In and around Baghdad, five bombs went off in commercial areas, killing eight civilians and wounding 35, two police officers said. Three medical officials confirmed the casualty figures.
All officials spoke on condition of anonymity as they were not authorized to release information.
The attacks came a day after Iraqi security forces reported progress in recapturing some areas in the western city of Ramadi, 130 kilometers (80 miles) west of Baghdad, from the Islamic State extremists who control large swaths of land in western and northern Iraq and in neighboring Syria. The Islamic State group has declared a self-styled caliphate on the territory under its control.
On Wednesday, the Iraqi security forces' advance was slowed by snipers, roadside bombs and booby-trapped buildings, military spokesman Brig. Gen. Yahya Rasool, told The Associated Press. Rasool said some of the families that were trapped in Ramadi had managed to flee the city and reached safe areas.
In May, the Iraqi government suffered a major blow when IS militants took over Ramadi, the capital of sprawling western Anbar province and Iraq's Sunni heartland. It was the government's biggest defeat since IS swept through areas in the country's north and west, including Iraq's second-largest city of Mosul, in the summer of 2014.
On Tuesday, Iraqi counterterrorism forces pushed into the Dubbat and Aramil neighborhoods, less than two miles from the city center, said Gen. Ismail al-Mahallawi, the head of operations in Anbar province.
The Iraqi air force and the U.S.-led international coalition were providing air support to troops on ground and bombing Islamic State targets, he said.
Hours after Iraqi government announced the gains, Col. Steve Warren, a spokesman for the U.S. military in Baghdad, said there were 250 to 350 Islamic State fighters in Ramadi, as well as several hundred outside the city on the northern and western perimeter.
"I think the fall of Ramadi is inevitable," Warren told Pentagon reporters, cautioning that it will take some time. "It's going to be a tough fight."
Since overrunning Ramadi, the Islamic State group has destroyed all the bridges around the city.
