Several hundred Syrian refugees who had been sheltering in a Lebanese town where the army and jihadists have been fighting crossed back into Syria on Friday, a nun assisting them said. Sister Agnes, a nun based in Syria, told AFP a first group of 350 of some 1,700 refugees who left the town of Arsal yesterday passed through the Masnaa border crossing back into Syria on Friday. The group set out from Arsal on Wednesday after a ceasefire between jihadists and the Lebanese military, following clashes that began on Saturday and have killed 17 soldiers and, reportedly, dozens of civilians. The departure appeared to be the first time a group of refugees has left Leba**n en masse to return to Syria.
