Scared locals have claimed that a military base was attacked by four triangular UFOs.
A video of the alleged alien onslaught left them horrified.
In the clip, scores of residents gather outside the air naval HQ as thunderous noises sound from within the perimeter walls.
One witness says “what the f*ck is that” after a loud explosion fills the air.
Another local says: “Something exploded. Could it have been devices inside the base?”
It happened at the Commander Espora Air Naval Base near Bahía Blanca, Buenos Aires, Argentina.
Gabriel Cena, who lives less than a mile from the base, said: “At 8.10 pm we started asking other residents if they knew what was happening.
“There was a series of shots, strong bursts, and explosions.
“The doors and windows to my house were shaking.
“It is not normal for there to be that level of shooting.
“There were several minutes of gunshots and a detonation, and then the sound of a helicopter.”
He added: “The official version cannot be that it was just some residents trying to invent news.”
The Commission for the Study of UFO Phenomena of the Argentine Republic, an organisation dedicated to investigating alleged alien sightings, stated that the events were an actual UFO attack.
CEFORA claimed to have information that there were four UFOs flying over the military base and that Argentine troops fired at them with anti-aircraft weapons.
The group said the alien spacecrafts were black and triangular in shape.
At least one UFO was firing a type of laser that injured two or three soldiers, according to the organisation.
Group spokesperson Andrea Pérez Simondini said: “We are collecting evidence and taking necessary action, requesting information from the authorities.
“We’ve also asked for radar readings from the Naval Base Mar del Plata and Espora Base as well as information on admissions to nearby hospitals.”
Pérez said witnesses saw “four lights entering the territory from across the ocean before taking a strategic position over one of the buildings where ammunition is stored”.
However, the military authorities have denied that the base was under attack and claimed that the videos were faked by unscrupulous locals.
Navy spokesperson Captain Germán Luis Zarralanga said their Sikorsky SH-3 Sea King helicopter was taking part in a training exercise that night, but was not involved in any kind of altercation with other aircraft.
When discussing the social media footage, the spokesperson said: “It’s an edit. I don’t know what their intentions were.
“Airport security and airport workers did not report seeing anything, and everyone at the base was sleeping except for the person piloting the helicopter.
“There was no type of special activity, no tactical manoeuvres, just a normal helicopter training flight, nothing related to ammunition.”
The debate rages on.
One local said: “Incredible! How many UFOs? I can’t believe it! Amazing. An interplanetary war has begun. We must leave the planet during this great invasion. Help…”
Lautaro asked: “Are you telling me that it was one of the first ever confrontations between humans and UFOs and we shot them down?”
Facundo joked: “It was The Avengers.”
