Despite Russia's President Vladimir Putin denying for months they would not invade, at around 4:30am local time today (February 24), the people of Ukraine began hearing explosions in the Ukrainian capital, Kyiv.
Since then many people have been fleeing their homes with many Brits living in the capital being told to leave whilst commercial flights were still available.
The BBC have since reported that they were able to verify a video which shows a "missile attack on an airport in western Ukraine."
