Syrian rebels captured the key Syrian city of Idlib from government forces, according to the Syrian Observatory for Human Rights.
The monitoring group said that the Ahrar al-Sham, Jund al-Aqsa and Nusra Front groups had taken the city on Saturday.
The Syrian government has not confirmed the loss, with state television saying, "The army is fighting fierce battles to restore the situation back to what it was."
The capture of the strategically important city would be a serious blow to President Bashar al-Assad's government.
