The alleged attack says it was Hezbollah at the airport (no offical sources can confirm this 100% given the fog of war), but they have also struck Syrian army positions and killed SAA soldiers who are trying storm a terrorist pocket near Golan Heights. Its a very common playbook by Israel to hit Syrian government forces before a terrorist offensive or to defend the terrorists when attacked. ISIS even apologized to Israel last when they accidentally shot at their forces if you listen to the Israeli defense minister.
