Russian military vehicles take part in a final rehearsal ahead of the May 9 Victory Day parade in Moscow. They do so after a wave of Ukrainian drone attacks closed airports across Russia, forcing the Kremlin to say it was taking "all necessary measures" to ensure the safety of foreign leaders set to watch the event. "We are from Rostov-on-Don. Nothing scares us...We have seen worse attacks", says 22-year-old student Valeria Pavlova while watching the rehearsal. Rostov-on-Don serves as a command and logistics hub for Russia's Ukraine offensive and has regularly been targeted. IMAGES AND SOUNDBITES
