Hezbollah has begun unleashing "game changing" waves of "lethal" nighttime drones against Israel, a defense expert warns, with the attacks contributing to casualties, defense breaches and plunging parts of the border region into chaos, according to reports.

Escalating deployments by Hezbollah had also prompted Prime Minister Benjamin Netanyahu to convene an emergency security meeting on May 30 following a surprise Hezbollah strike, amid reports of "utter chaos" as Israeli forces scrambled to respond.

"These nighttime drones are the very small Category 1 and Category 2 drones," defense expert and Draganfly CEO Cameron Chell told Fox News Digital.

"They are generally used by squads on the ground to go and conduct tactical lethal missions or surveillance missions right in theater immediately. What they are able to do is use thermal sensors to be able to fly at night and use heat signatures to spot IDF troops," he said.

"Hezbollah now has nighttime capabilities, which is game changing," Chell added.

"What you will see is an escalation of the use of drones and the innovation of asymmetric warfare in that particular area by Hezbollah," he warned.

Chell’s comments came amid reports of makeshift defenses with nets being deployed against the backdrop of a significant shift in the conflict.

Israeli soldiers have resorted to buying commercial fishing and soccer nets to entangle the incoming aerial threats, according to reports.

"This means that there is a whole other set of countermeasures that the IDF has to put in place, whether it is electronic jamming, net guns or the use of netting just to put in front of installations or in front of vehicles to try to stop the final impact of the drone if it is a strike drone," Chell added.

"The IDF will have to change a lot of their tactics regarding their ability to move around and conduct operations at night. Now they will have to factor in the fact that Hezbollah has nighttime capabilities to at least do observation using thermal cameras, as well as strike capabilities."

Netanyahu called a meeting with top officials following an intense Hezbollah rocket and drone blitz that caught the military off guard on Saturday.

According to a report by Channel 13, the Israeli army was surprised by the scale of the fire as well as Hezbollah's decision to shift its operational policy in response to the expansion of Israel’s ground operations beyond the Litani River.

Reports from the ground described "utter chaos" in parts of the north. While rockets were said to have hit the cities, Hezbollah simultaneously launched waves of drone strikes.

Hezbollah leader Naim Qassem has also touted the militant group’s drone capabilities, calling them an effective weapon against Israeli forces operating near and inside southern Lebanon

Netanyahu has also described Hezbollah's drone capabilities as a major threat given the difficulty in detecting them.

"Hezbollah have got a supply line or supply chain of some sort set up," Chell added before stating that they are not "using stuff that is groundbreaking; this is very old technology and tactics that they are using."

"That said, somebody is making the equipment available to Hezbollah — whether it is coming via Iran, China, Russia, Afghanistan or the black market, someone is getting enough product and feeding it into their supply chains," Chell warned.
