July 28 (UPI) -- NATO aircraft were scrambled Sunday night to respond to a Russian attack on Ukraine, the Polish military said Monday.
"Polish and allied quick reaction aircraft were scrambled, and ground-based air defense and radar reconnaissance systems reached the highest state of readiness," Poland's Operational Command of the Armed Forces said in a statement.
"These actions are preventive in nature and are aimed at securing airspace and protecting citizens, especially in areas adjacent to the threatened region."
A few hours later, it issued a statement that the aircraft had concluded their deployment, adding that "no violations of Polish airspace were observed."
Swedish fighter jets stationed in Poland were among the aircraft scrambled, it said.
