US-backed Syrian forces have breached the wall at Raqqa's Old City as they try to retake the city from Daesh, the BBC reported, quoting the US military.
It says the coalition helped the advance of the Syrian Democratic Forces (SDF) by firing on two sections of the historic Rafiqah Wall.
The SDF, supported by US-led coalition air strikes, has spent months encircling the city.
Daesh seized Raqqa in 2014, proclaiming it the capital of a "caliphate".
"Coalition forces supported the SDF advance into the most heavily fortified portion of [Raqqa] by opening two small gaps in the Rafiqah Wall that surrounds the Old City," the US Central Command said in a statement. 
Last week, the SDF said its fighters had fully encircled Daesh in Raqqa.
