Vladimir Putin ordered the invasion on February 24, 2022.
The Russian invaders have made military gains in eastern Ukraine, but their early objective of capturing their neighbouring country in days, if not weeks, has not come to pass.
The Russian army has recalibrated its strategy after heavy losses, moving away from the capital Kyiv and Kharkiv, Ukraine's second biggest city, to Donetsk in the east.
Western support for Ukraine has lagged in May in comparison to March and April, and there have been calls for Volodymyr Zelenskyy's government to negotiate a truce with the Kremlin, which the Ukrainians have rightly rejected.

Chernihiv, northeast of Kyiv, was an early target of Russia's offensive after its invasion.
When they failed to capture the city, Russian forces battered large parts of Chernihiv and the surrounding regions.
