BEIRUT — U.S.-led coalition aircraft unleashed a series of airstrikes targeting the Islamic State group's stronghold of Raqqa in eastern Syria, killing at least 10 militants and wounding many others in one of the largest coalition operations carried out in Syria to date, the coalition said Sunday.
At least 16 airstrikes were reported late Saturday and early Sunday, triggering successive explosions that shook the city and created panic among residents, activists said. The U.S.-led coalition often targets IS-held towns and cities in Syria, but the overnight strikes on Raqqa were rare in their intensity.
In a statement issued early Sunday, the coalition said it had conducted 16 airstrikes throughout Raqqa, destroying vital IS-controlled structures and transit routes in Syria.
"The significant airstrikes tonight were executed to deny Daesh the ability to move military capabilities throughout Syria and into Iraq," said coalition spokesman Lt. Col. Thomas Gilleran, using the Arabic acronym for the Islamic State group.
"This was one of the largest deliberate engagements we have conducted to date in Syria, and it will have debilitating effects on Daesh's ability to move" from Raqqa.
Raqqa is the de facto capital of the so-called Islamic caliphate declared a year ago by the Islamic State group in territories it controls in Iraq and Syria.
An IS-affiliated militant website confirmed the strikes on the center of the city, saying 10 people were killed and dozens wounded. It also published purported photos of dead victims, including two of young boys suggesting they were civilians.
A Raqqa-based anti-IS activist network reported eight civilians were killed by the coalition airstrikes, including a 10-year-old child. The report could not be independently confirmed.
The network, called Raqqa is Being Silently Slaughtered, said at least one airstrike targeted a group of IS members in the city center. Another targeted an IS checkpoint while a third destroyed large parts of an IS-held brick factory in the city.
In the remote northeastern city of Hassakeh, IS suicide bombers detonated an explosives-laden truck near a main power plant Sunday. State-run news agency SANA reported casualties and material damage in the power plant on the southern edge of the city.
Fighting has raged in Hassakeh since the IS group attacked several southern neighborhoods held by government troops earlier this month. The violence has forced tens of thousands of residents to flee. The predominantly Kurdish city was split between government forces and Kurdish fighters, who have been fighting the IS group separately.
The coalition regularly targets the Islamic State group, which controls about a third of Iraq and Syria.
In Iraq, a Defense Ministry statement said government forces repelled an IS attack on a town and a vital dam in Anbar province after IS fighters launched an offensive on the town of Haditha and the nearby Haditha dam Sunday morning.
At least 20 militants were killed in the failed attack, said the statement, which did not provide any further information.
Iraqi forces, backed by Shiite militias, have been struggling to recapture areas lost to the IS group in the country's west and north.
In May, the militant group scored a stunning victory, overrunning Ramadi, the provincial capital of western Anbar province. Yet, Haditha and some other towns remain under control of government forces and allied Sunni tribal fighters.
