Russia sent many things. They hit Ukraine's power. This made power go out. People are worried.
The power system was a big target. Russia wants to stop power. They want to make it cold. This is a bad plan.
Kyiv lost power. Some houses broke. Fires and some people died. A child died too.
Poland sent planes. They fly near Ukraine. They want to keep Poland safe. This is a big problem.
Russia makes life hard. Winter will be very cold. Peace is far away.
