Ursula von der Leyen is the president of the European Commission. She was flying to Bulgaria. Her plane had a problem with the GPS. The GPS stopped working before the plane landed. The pilots used paper maps to land the plane safely.

The European Commission said that Russia may have caused the problem. They said Russia often tries to make trouble. The Bulgarian government also said the GPS did not work because of interference. They helped the plane land with other tools.

Many people are worried about these problems. Experts say Russia has done this before. They say it is happening more since the war in Ukraine. Ursula von der Leyen visited Bulgaria to talk about safety and defence. She saw the problems herself.
