Israel's army said on Saturday it killed a key operative in Hezbollah's Aerial Defense Unit in eastern Lebanon, accusing him of carrying out numerous attacks against Israelis.
In a statement, the army identified the Hezbollah member as Meitham Mustafa al-Attar, saying that he had visited Iran several times, "where he gained knowledge and assisted in building up Hezbollah's force and arsenal of Iranian weapons."
Lebanese state media said al-Attar's car was attacked in a drone strike in the town of Shaath, north of Lebanon's eastern city of Baalbek.
Hezbollah confirmed the killing of the 33-year-old but did not specify his role in the movement.
The Iran-backed group and Israel have been trading fire for nearly nine months in hostilities that have played out in parallel to the Gaza conflict, raising fears of an all-out war between the heavily armed adversaries.
Hezbollah has said its campaign of rocket and drone attacks on northern Israel has aimed to support Palestinians under Israeli bombardment in Gaza.
