A number of unmanned aerial vehicles are being used to conduct surveillance and reconnaissance missions over Israel's gas fields in the Mediterranean Sea, officials said.
A decision to deploy the UAV's is mainly out of concern that Hezbollah may try to target the gas fields.
In July the cabinet approved the demarcation of Israel's northern maritime border with Lebanon to combat Lebanon's claims to offshore territories that Israel claims it owns.
The move set the economic rights of the gas fields.
The army decided to deploy the drones and maintain a 24 hour presence over thegas field after Hezbollah deputy chief Naim Qassem warned it would protect Lebanon's maritime sovereignty in order to "regain its full rights."
In June last year the Leviathan offshore gas field located in the Mediterranean sea roughly 81 miles west of Haifa was discovered and described as one of the world's largest offshore gas finds.
In 2009 the Tamar gas field also in the Mediterranean some 50 miles west of Haifa was discovered.
