The mysterious flash that lit the sky over Kyiv caused confusion, alarm and speculation about its cause.
Four short videos posted on a Telegram channel, by blogger and journalist Anatolii Sharii, showed the sky above the Ukrainian Capital suddenly lit up.
Sergiy Popko is the head of the military administration in the city. He described the app as having a “bright glowing” glow.
He claimed that an air raid warning was activated, but “air defense was not operational”.
In one clip it appeared that a burning object was crashing down to the ground.
The Ukrainian air force is aiming to shoot down the missiles and drones launched by Russia. They believe a satellite falling from orbit or meteorites could be at fault.
It said that there was no danger of an enemy using air-attack weapons at the moment.
Minutes before, presidential adviser Andriy Ermak posted an emoji depicting a UFO.
As they speculated on the cause of this glow, social media users responded with memes.
Please do not use the official symbols of the air force to create memes that are enjoyed by your enemies! The Ukrainian air force sent a message.
The Austrian ambassador in Kyiv shared a video and made jokes about those who suggested it was an alien craft on Twitter.
Citing what they called preliminary information, the city’s military administration said that it was a crashing NASA Satellite.
The US space agency has denied this and stated that there was confusion about its announcement made earlier this week, which said it was taking a retired satellite out of orbit.
The satellite, which was launched in 2002 for the purpose of studying the sun’s rays, was still in orbit when the flash occurred.
