Have you seen the video of the Russian bridge that got blown up on Saturday? It's a 12-mile bridge, the longest in Europe. Russia built it after they annexed Crimea in 2014, and it's their only direct link to get supplies in with railroad cars.
There's also a video that shows a section of the bridge on fire. Russia claimed it was a truck bomb, but some experts think a boat under the bridge may have been packed with explosives. So far, Ukraine hasn't admitted to blowing it up.
It shows Leonardo DiCaprio and Kate Winslet's famous pose from "Titanic", but they're on the edge of a partially destroyed bridge. Here's a photo.
