Ukrainian droneks set Russian arms depots ablaze, destroying what Ukraine said were thousands of tons of weaponry, ahead of Zelensky's White House visit.

Russia said it was working to repel a Ukrainian drone attack on Toropets, where there's a major military depot, as explosions lit up the night.

Russian reports say Ukrainian drones have struck a Russian arms depot deep inside the country, triggering explosions and the closure of a major highway.
