"Certainly, for the Romanian President, this will be, one way or another, the number one topic on his mind, for obvious reasons," said Prime Minister Donald Tusk in a conversation with journalists before the EU-Western Balkans summit in Montenegro, when asked about the drone incident that occurred in Romania.

"For us, it is not a surprise. As you know, we are prepared. I also warned our European partners many weeks ago that various incidents, escalations, sometimes intentional, sometimes not, could be expected, but that the situation is generally moving towards escalation and greater tensions. Therefore, we must be prepared for this, and Poland is trying to be prepared," he continued.
