NATO country and U.S. ally Poland warned its citizens Thursday to immediately flee Iran, with its prime minister saying the "possibility of a conflict is very real."
The remarks from Donald Tusk come as the U.S. has been bolstering its military presence in the Middle East with tensions escalating over Iran’s nuclear program.
"Please leave Iran immediately and under no circumstances travel to this country," Tusk said Thursday in the town of Zielonka outside of Warsaw, according to USS Gerald R. Ford, and its strike group are moving from the Caribbean toward the Middle East.
The move would place two aircraft carriers and their accompanying warships in the region.
The USS Abraham Lincoln and three guided-missile destroyers arrived in the Middle East more than two weeks ago.
On Wednesday, U.S. Central Command posted photos showing F/A-18 Super Hornets landing on the decks of the USS Abraham Lincoln in the Arabian Sea.
"When launched from a catapult on an aircraft carrier, the Super Hornet can go from a full stop to airborne in under three seconds," CENTCOM said.
