Russia launches a large-scale invasion of Ukraine on February 24, 2022.
The invasion is preceded by a Russian military buildup in occupied Crimea and around Ukraine, and by Russia's recognition of the breakaway separatist regions in eastern Ukraine.
The invasion is the largest conventional military attack in Europe since the Second World War.
At about 06:00 Moscow time, Putin announces a "special military operation" in eastern Ukraine; minutes later, cities of Ukraine are attacked by missiles.
Two hours later, Russian ground forces enter the country.
The invasion is met with widespread international condemnation, with further sanctions against Russia
Anti-war protests in Russia are met with mass arrests.
