U.S.-backed forces breach Raqqa's old city in Syria, coalition says

WASHINGTON (Reuters) - U.S.-backed Syrian Democratic Forces have breached the old city in Syria's Raqqa after the U.S.-led coalition fired on two small sections of the historic Rafiqah Wall, allowing them to overcome Islamic State defenses, the coalition said on Monday. "The portions targeted were 25-meter sections and will help preserve the remainder of the overall 2,500-meter wall," the coalition said in a statement.
