Poland shot down Russian drones that had entered its air space, the most far-reaching intrusion ever into NATO territory. The Netherlands assisted Poland. Donald Tusk, the Polish prime minister, said the incursion brought NATO closer to “open conflict” with Russia. Poland had earlier decided to close its border with Belarus while Russia conducts its Zapad war games there, which simulate an attack on NATO. Analysts think the previous Zapad manoeuvres in 2021 were a training ground for Russia’s invasion of Ukraine. Mr Tusk said a Belarusian spy had been arrested and a diplomat would be expelled.
