“Jellyfish UFO” or a stray bag? Sirens sounded in northern Israel over an unknown aerial object
On the evening of October 10, an unknown aerial object came from the direction of Lebanon into Israel's northern border region and set off an air-raid alert in a border village. The Israeli military searched for it all night with helicopters, but even after twelve hours it had not found it and could not identify it. Since then, an image has been circulating on social media as a “jellyfish-shaped UFO,” while the authorities are considering a drone, a paraglider and even a windblown bag.
The footage was recorded by a security camera in the border area on the evening of the alert. It was first published by the Israeli news site ynet.
What to look for in the footage? Nothing indicates the object's size, because there is no reference point of known size next to it, so a nearby bag and a distant drone can look the same size. It is worth watching whether it drifts steadily, like something carried by the wind, or changes direction and holds its altitude, like a controlled device. In nighttime camera footage, lights and motion blur easily, and shapes can be deceptive.
Alert in a border village
On Saturday evening, October 10, at 7:57 p.m., an air-raid siren sounded around Arab al-Aramshe. The village lies in the Western Galilee, right next to the Lebanese border. Israel's Home Front Command issued the alert over the infiltration of a hostile aircraft and sent residents to protected rooms. Nine minutes later came the notice that they could leave the shelters.
According to the first statement from the Israeli military (IDF), border surveillance systems detected an unidentified aerial object near the Lebanese border. The troops combed the area but said they found nothing unusual. No special instructions applied to the population.
An all-night search
The search did not stop. According to ynet's report, security forces deployed to about 17 communities in the Western Galilee, including Nahariya, Shlomi and Rosh HaNikra. Helicopters joined in during the night. For a while they also examined whether someone had arrived by sea near Nahariya, but this was ruled out.
On Sunday morning the search continued on the ground and in the air. More than twelve hours after the alert, the military had still not identified the object, nor had it confirmed whether anything had actually crossed the border. Moshe Davidovich, head of the area's regional council, requested an immediate meeting with the head of Northern Command and a full investigation.
How did it become a “jellyfish”?
Alongside ynet's video, a photo also began circulating in local media on Sunday, but the reports do not say exactly who took it.
On international UFO sites, the footage quickly took on a life of its own. A Chinese news site said the object resembles a jellyfish, and a Brazilian UFO site was already describing it as a jellyfish-shaped UFO that set off alerts in Israel. These sites do not mention the ordinary possibilities being examined by the authorities.
What do the authorities think?
Three possibilities appear in the official and semi-official reports:
- A drone of unknown type. According to ynet, the military is examining whether it was a drone model unknown to Israel.
- A powered paraglider. A military source told the news site Walla that this cannot be ruled out either.
- A bag or a balloon, meaning a false alarm. As early as Saturday evening, Channel 12 reported that the local control center had identified a foreign object, apparently a bag, that was small and moving slowly. This was not officially confirmed later either.
The military has not ruled out a security incident either. In recent years, real attack drones have repeatedly come across the Lebanese border, so the authorities take every signal seriously.
The sober take
The incident is real: an unknown aerial object really did trigger an alert, and the military really could not identify it. It is worth separating, however, what the authorities say from what the UFO sites add.
- The “jellyfish” is a description of a photo, not an observation. Nowhere in the official reports does it say the object was jellyfish-shaped. It is an interpretation of a circulating image whose source is not even known. The word “jellyfish” sounds familiar in the UFO community because a military infrared video recorded over Iraq and released in 2024 was also given this name. The parallel comes from the name, not from the object.
- Small, slow, carried by the wind: this is the most common case. A slowly drifting balloon or plastic bag with dangling parts can easily take on a “tentacled” shape in nighttime camera footage. This is not rare: in February 2023, the U.S. Air Force shot down several unknown objects over North America, at least one of which, according to the investigations, was probably a hobby balloon. An air defense system detects motion and signal, not shape.
- A wartime environment, sensitive systems. On the Lebanese border, air defenses are set to be very sensitive because of real drones. In such conditions a false alarm is not a malfunction but the price of the system: better for the siren to sound over a bag than for a real drone to go unnoticed.
- “Unidentified” here is military terminology. It means the military does not know what it was, not that it was something extraordinary. If a small object is not found in a wooded, hilly border region, that in itself is not surprising.
In summary: the story is real in the sense that an unknown object triggered an alert and has not been identified to this day. Based on the available information, the most likely explanation is a small drone, a paraglider or a windblown object. The “jellyfish UFO” label is a product of online spread, not of the investigation.
