Hizbollah has repeatedly denied any connection to a drone which was shot down west of Haifa last Thursday evening.
According to the IDF, Israeli radars monitored the unmanned aerial vehicle as it flew out of Lebanese territory and over the Mediterranean.
As the drone turned east towards the Israeli coast, Israel Air Force F-16 fighter jets were scrambled and, after visual confirmation that the aircraft was unmanned, the order was given to shoot it down over the sea.
Israeli officials said that the drone was almost certainly of Iranian design and probably belonged to a special reconnaissance unit operated by Hizbollah under the guidance of the Iranian Islamic Revolutionary Guards.
