The hatred between Sunni "Syria" and Shiite-controlled "Lebanon" is growing, a battle between the Julani terrorists and the "Lebanese Army" on the shared border, with casualties on the Lebanese side.
It is not clear how many casualties, there are conflicting reports. This broke out after Syrians infiltrated Lebanon, and it turned out that they were from the ISIS militias.
It could be that the ISIS/Julani terrorists are preparing for the next stage: a break into "Lebanon" in order to fight the Shiites.
From our point of view, this is an excellent situation, and at the right time: when we eliminate Hezbollah - its terrorists will not be able to escape to Syria, as in the past; and we have every justification to remain in southern Lebanon, since the jihadists are plotting to conquer Lebanon, or to incite it, and we must defend our territory.
