An air strike in Syria in December 2015 killed a prominent Hezbollah leader, Samir Qantar. Israel welcomed Qantar’s death, saying he was preparing attacks from Syrian soil, but stopped short of confirming responsibility for eliminating him.
Earlier that year, an Israeli air strike in Syria killed six members of Hezbollah, including a commander and the son of the its late military chief Imad Moughniyah near the Golan Heights.
Israeli defence officials have voiced concern that Hezbollah’s experience in the Syrian civil war, where it has played a significant role and recently helped the Syrian army regain the eastern sector of the city of Aleppo, has strengthened it.
Rebels operating in the area have said Hezbollah’s major arms supply route into Damascus from the Lebanese border has been targeted on several occasions in recent years by air strikes. This has included strikes on warehouses and convoys of weapons.
