Poland, a NATO member and U.S. partner, urged its citizens on Thursday to depart immediately, as the Prime Minister stated that the likelihood of conflict is highly probable.

Donald Tusk’s comments coincide with the United States increasing its military forces in the Middle East amid rising tensions regarding the situation.

“Please exit Iran immediately and do not travel there under any circumstances,” Tusk stated on Thursday in Zielonka, near Warsaw, according to reports. “I do not intend to cause alarm, but we are all aware of what I mean. The prospect of a conflict is very real.”

“Evacuation might become impossible within a few, a dozen, or several dozen hours,” Tusk reportedly added.

The world’s largest aircraft carrier and its strike group are currently relocating from the Caribbean to the Middle East.

This deployment will result in two aircraft carriers and their supporting warships being stationed in the region.

A carrier group and three guided-missile destroyers reached the Middle East over two weeks ago.

On Wednesday, the U.S. Central Command released images depicting F/A-18 Super Hornets touching down on the USS Abraham Lincoln in the Arabian Sea.

“When catapulted from an aircraft carrier, the Super Hornet can transition from a complete standstill to airborne in less than three seconds,” CENTCOM noted.
