Russian warships displayed for Navy Day in St Petersburg, Russia

Footage shows Russian warships being displayed on the Neva River during a rehearsal for the Navy Day celebrations in Saint Petersburg, Russia.

The annual national holiday honoring the sailors in units of the Russian Navy and its specialized arm takes on extra significance amid the country's ongoing war with neighboring Ukraine, which has claimed the lives of an estimated 25,000 Russian soldiers. It will be marked on July 31.
