Prince William paid a surprise visit to the Rzeszow military base in southeastern Poland.

According to APA's British office, he thanked the British soldiers.

Prince William's visit has been kept secret for security reasons.

The military base is located near the Ukrainian border.

"Thank you for everything you are doing here. You are doing a really important job here. It is really important to defend our freedom. Everyone supports you," he said.

It should be noted that Rzeszow is located more than an hour away from the Ukrainian border.

British troops are there to help secure Polish airspace.
