Decorations have been going up in Moscow as the country commemorates the 80th anniversary of the victory over Nazi Germany
The attacks in Russia and Ukraine come just two days before a ceasefire in Ukraine - unilaterally announced by Russia last month - is due to begin.
The ceasefire is set to run between 8 May and 11 May - overlapping with Russia commemorating Victory Day.
Unlike Britain, France and the US - which celebrate VE (Victory in Europe) Day on 8 May - Russia commemorates Nazi Germany's surrender the following day, as Germany officially signed the document by the time it was 9 May in Russia.
The huge parade of weapons and tanks in Moscow's Red Square has long been seen as a chance for the Kremlin to put its military might on display.
The event typically draws high-level guests - but Ukraine's president warned at the weekend that he couldn't guarantee the security of foreign officials planning to attend the parade on Friday.
Last month, both Ukraine and Russia accused each other of breaching a 30-hour Easter ceasefire announced by Putin. And as our next post explains, Ukraine has dismissed the ceasefire due to begin on Thursday.
