Rubio calls Russian drones over Poland 'unacceptable' but declines to say it was intentional

Nato announces plans to beef up defense as Poland rejects Trump's suggestion drones were sent by mistake

The US secretary of state, Marco Rubio, on Saturday said the incursion of Russian drones into Polish airspace this week was unacceptable but that it remained unclear whether Russia had deliberately sent the drones into Polish territory. Nato announced plans to beef up the defense of Europe's eastern flank on Friday, after Poland shot down the drones that had violated its airspace, the first known shots fired by a member of the western alliance during Russia's war in Ukraine.

We think it's an unacceptable and unfortunate and dangerous development," Rubio told reporters before departing on a trip to Israel and Britain.
