Russia's Victory Day parade, which celebrates the Soviet Union's Second World War victory, is underway in Moscow.

The Victory Day in Russia – an annual commemoration – is the country’s most important holiday and a source of national pride, marked by a huge parade of soldiers and military hardware through Red Square.

Russian President Vladimir Putin in his speech said troops and volunteers in the eastern Ukrainian Donbas region were "fighting for the motherland, its future" and he accused the West of preparing for an "invasion of our land".

Here's a look at what we're seeing so far.
