Romania summoned Russia's ambassador to Bucharest Sunday after it became the second NATO country in less than a week to report a Russian drone incursion in its airspace.
The big picture: Tensions have heightened in Eastern Europe since Poland reported that NATO and Polish jets scrambled to intercept Russian drones that breached its airspace last week during Russia's war on Ukraine, and an EU official on Sunday denounced the latest violation as a "reckless escalation."
