NATO country orders citizens to immediately evacuate Iran, warning 'possibility of a conflict is very real'

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 Turkey's Anadolu Agency. "I do not want to alarm anyone, but we all know what I am referring to. The possibility of a conflict is very real." 

"In a few, a dozen, or several dozen hours, evacuation may no longer be possible," Tusk reportedly added.
