Poland Says It Shot Down Russian Drones That Entered Its...

There was no immediate comment from Russia’s defense ministry. At least three Polish airports were temporarily closed because of the military operation, including the country’s biggest, Warsaw Chopin Airport, according to notices posted by the Federal Aviation Administration in the United States. The Polish military advised people to stay at home. It said the biggest threat was in Poland’s eastern provinces, including Podlaskie, on the border with Belarus; the province of Masovia, which includes the capital, Warsaw; and Lublin, which borders both Belarus and Ukraine. Russia’s full-scale offensive in Ukraine is in its fourth year, and it has recently ramped up its drone and missile attacks on the country, despite efforts by the United States and other countries to broker peace. On Sunday, Russia launched its largest drone assault so far in the war, the Ukrainian authorities said. After that attack, the Trump administration said it was prepared to increase economic pressure on Russia to get it to negotiate. President Trump has grown increasingly frustrated with President Vladimir V. Putin of Russia, who has given little indication that he is ready to ease his maximalist demands to end the conflict.
