The Syrian army, Hezbollah and the Lebanese Army have launched a coordinated operation against Hayat Tahrir al-Sham (formerly Jabhat al-Nusra, the Syrian branch of al-Qaeda) and ISIS at the Syrian-Lebanese border.
The goal of the operation is to end militant presence in the Lebanese town of Arsal and the Syrian village of Fleeta.
The military operation followed a series of attempts of the Lebanese government to negotiate with militants in the area and to push them to withdraw from the Lebanese border to the Syrian militant-held province of Idlib.
