When an armed quadcopter buzzed over Lebanon’s southern border into Israel on May 19, one Israel Defense Forces (IDF) soldier raced up a nearby hill and attempted to snag the drone’s fiber-optic control cable with a piece of scrap metal.The remarkable scene captured by photojournalists at the militarized border provided the clearest example yet seen of the fiber-optic drones -- first pioneered by Russian soldiers and now ubiquitous in Ukraine -- being used by Iranian-backed Hezbollah militants.It also highlights the vulnerability of even the world’s most advanced militaries to the cheap drone innovation.

In the past month, Hezbollah militants have killed three IDF soldiers and one Israeli civilian using kamikaze drones controlled through kilometers-long fiber-optic cables.In response, Israel’s Prime Minister Benjamin Netanyahu announced the formation of a team to counter the tethered drone threat. Israel is furnishing the task force with an “unlimited budget,” amid growing controversy in the country over the lack of preparedness for a weapon that first emerged in 2024.The IDF reportedly declined earlier offers from Kyiv to train Israeli forces in anti-drone techniques, but on May 17, Netanyahu claimed he warned of the threat of weaponized quadcopters years before the current crisis over the devices.“After I saw the war in Ukraine, I thought this could also serve as a tool on our battlefield,” Netanyahu said at a government meeting.
