Russia and Ukraine are fighting at sea. They are attacking each other's ships in the Black Sea. Ukraine wants to stop Russia from sending supplies to Crimea. Our reporter went on a Ukrainian Navy ship to see what's happening. The sailors are always ready to fight because Russian attacks can happen at any time.
The Ukrainian Navy is trying to protect its ships, but it's hard to stop Russia from attacking civilian ships. Many ships have been hit, and it's a big problem. Ukraine is a big exporter of grain, and the war is making it hard to get the grain to other countries.
People who live and work near the ports are in danger. Some have been hurt or killed by Russian missiles. The war is making life very difficult for them. They hear sirens and see drones every day. It's a very scary time for them.
