WARSAW, Poland — NATO said Friday it’s bulking up its defensive posture on its eastern flank bordering Belarus, Russia and Ukraine with new equipment to deter potential Russian aggression following an incursion by Russian drones into Polish territory.

The alliance’s supreme commander in Europe said a new operation, dubbed Eastern Sentry, will add equipment from France, Denmark, Germany and the U.K. to its existing air and ground-based defenses.

“The key to this is an entirely new defense design,” U.S. Gen. Alexus Grynkewich told reporters at the alliance’s Brussels headquarters.

French Rafale fighter jets, Danish F-16s, a frigate and ground-based defense systems have been pledged for the operation.

Grynkewich said the additional resources will enable the alliance to “plug gaps in the line” and concentrate forces wherever they’re needed while improving communications across NATO’s entire eastern flank.

French President Emmanuel Macron said he would deploy three Rafale fighters to Poland, while Britain unveiled fresh sanctions on Russia’s oil revenues and war machine.

“The security of the European continent is our top priority. We will not yield to Russia’s growing intimidation,” Macron posted on X. He said the deployment was discussed with both NATO Secretary-General Mark Rutte and British Prime Minister Keir Starmer.

Poland’s Defence Minister Wladyslaw Kosiniak-Kamysz hailed the operation in a post on X as “active deterrence and readiness to defend wherever needed.”

Blame Moscow

Multiple Russian drones crossed into Poland on Wednesday, prompting NATO to send fighter jets to shoot them down and underlining long-held concerns about Russia’s three-year war in neighboring Ukraine expanding.

Russia said it did not target Poland and Moscow’s ally Belarus said the drones went astray because they were jammed, but European leaders have expressed certainty that the incursions were a deliberate provocation by Russia.

Britain backs Kyiv

British Foreign Secretary Yvette Cooper made her first trip to Kyiv on Friday after her appointment a week ago following a Cabinet shake-up by Starmer.

Cooper said her visit is a demonstration of solidarity with Ukraine, which she said has seen a massive increase in Russian drone attacks in recent months. In July, there was a tenfold increase over the same month last year, she said.

“The UK will not stand idly by as Putin continues his barbaric invasion of Ukraine,” Cooper said, noting what she said was the Russian president’s “complete disregard for sovereignty” by sending drones into NATO airspace.

“International action to increase economic pressure on Russia and to cut off critical cash flows which he desperately needs to pay for this illegal war is vital.”

Reflecting Britain’s support for Ukraine, Prince Harry made a surprise visit to Kyiv where he met with wounded service members on Friday.

Ukrainian drones hit

Russian air defenses downed 221 Ukrainian drones over more than a dozen Russian regions early Friday, Russia’s Defense Ministry said. The attack involved some of the highest numbers of drones reported by the Russian military, but there have been no reports of any significant damage.

A Ukrainian security official said drones struck Russia’s largest oil port on the Baltic Sea in Primorsk, including oil pumping stations conveying oil to the Ust-Luga port terminal.

The official said Primorsk is a key hub for Russia’s “shadow fleet” of sanction-busting tankers that earn Moscow approximately $15 billion annually.
