Slovakia will stop sending power. This is for Ukraine. It happens if oil does not come.
The oil is from Russia. It comes by a big pipe. The pipe is called Druzhba.
Slovakia has no energy. They think Ukraine stopped the oil. This is not good.
The oil stopped in January. Ukraine says a drone hit pipes. The pipe is important for Slovakia.
Slovakia's leader is not happy. He says Ukraine is bad. Slovakia will lose money.
Less power for Ukraine is bad. Slovakia gave Ukraine much power. Ukraine needs this power.
Hungary also uses the pipe. This shows energy is important. We wait to see what happens.
