Late on October 26, eight mysterious attack helicopters carried out a series of airstrikes on positions in on the northern Syrian governorate of Idlib near the border with Turkey.
Opposition activists said that the helicopters, which came from Turkey, attacked several positions in the outskirt of the town of Barisha in the northern Idlib countryside. Some reports claimed that an air landing also took place west of the town. However, this is yet to be confirmed.
The origin of the helicopters has not been determined, yet. However, most sources are claiming that they were U.S.-led coalition helicopters.
Earlier this year, the U.S.-led coalition resumed operations against al-Qaeda-affiliated groups in Greater Idlib, targeting a headquarters of Horas al-Din. Later, a headquarters of so-called Ansar al-Tawhid in eastern Idlib was targeted.
Unconfirmed reports claim that the helicopters attacked several positions of Horas al-Din. The upcoming hours will likely reveal more information about the mysterious attack.
