Polish and allied aircraft were deployed early on Saturday to ensure the safety of Polish airspace after Russia launched airstrikes targeting western Ukraine near the border with Poland, armed forces of the NATO-member country said.
"Polish and allied aircraft are operating in our airspace, while ground-based air defence and radar reconnaissance systems have been brought to the highest state of readiness," the operational command said in a post on X.
At 0340 GMT, nearly all of Ukraine was under air raid alerts following Ukrainian Air Force warnings of Russian missile and drone attacks.
It follows allegations by NATO member Estonia of a violation of its airspace by three Russian military jets on Friday, in what it called an "unprecedentedly brazen" incursion, the latest in a series of recent military actions by Russia that have rattled the alliance.
Russia's Defence Ministry denied its jets violated Estonian airspace, saying they flew over neutral waters.
With tensions already high because of the war in Ukraine, the incursion came just over a week after more than 20 Russian drones entered Polish airspace on the night of September 9-10. That prompted NATO jets to down some of them and Western officials to say Russia was testing the alliance's readiness and resolve.
It also occurred three days after Russia and Belarus ended their "Zapad-2025" joint military exercises, which included the rehearsal of the launch of Russian nuclear weapons.
Tallinn said the three MiG-31 fighter jets entered Estonian airspace without permission and stayed for a total of 12 minutes before they were forced to withdraw, during which time the high-speed aircraft could have traversed broad swaths of the country.
"Russia has violated Estonian airspace four times already this year, which is unacceptable in itself, but today's violation, during which three fighter jets entered our airspace, is unprecedentedly brazen," Foreign Minister Margus Tsahkna said.
Russian jets routinely fly over the Baltic Sea between mainland Russia and its exclave of Kaliningrad.
In a statement issued early on Saturday, the Russian Defence Ministry said its jets flew over neutral waters of the Baltic Sea in proceeding from northwest Russia to Kaliningrad.
"The flight was carried out in strict conformity with international rules governing airspace with no violation of the borders of other states as is confirmed by independent checks," the ministry said of the three MiG-31 fighters in a post on Telegram.
"During the flight, the Russian aircraft did not deviate from the agreed flight path and did not violate Estonian airspace."
Separately, Poland said on Friday two Russian fighter jets violated the safety zone of the Petrobaltic drilling platform in the Baltic Sea.
EYES ON TRUMP
US President Donald Trump said late on Friday afternoon he had not been briefed on the incident but expected he would be later.
"I don't love it. I don't like when that happens," Trump told reporters when asked if he saw the incursion by Russian jets as a threat to NATO. "Could be big trouble. I'll let you know later."
Trump's administration is being closely watched for a response.
