Ukrainians are marking the fourth anniversary of what has become Europe's bloodiest conflict since the Second World War in ceremonies in Kiev and across the country.

Fierce Ukrainian resistance and hundreds of billions of dollars in Western military aid have prevented Russia from achieving what it thought would be an easy victory.

This is how the start of the invasion was reported on the BBC.

Explosions have been heard across Ukraine in cities including the capital Kiev.

In an address to mark the anniversary, the Ukrainian president, Volodymyr Zelensky, vowed that his country would never yield to Russian aggression.

In those four years, hundreds of thousands have been killed and millions of Ukrainians have been forced to flee their homes.

Our correspondent Paul Adams is in a place of great significance for Ukrainians.

Listeners may recall in the immediate weeks after the full-scale invasion that this is where Russian troops came.
