Polish PM vows military upgrade after Russian drone incursion

Polish Prime Minister Donald Tusk on Thursday pledged to push ahead with a “great modernisation programme” for his country's military, a day after Russian drones crossed into Poland and forced the NATO alliance to confront a potential threat in its airspace for the first time.

European officials described Wednesday's incursion, which occurred during a wave of unrelenting Russian strikes on Ukraine, as a deliberate provocation.

It deepened longstanding fears that the three-year war between Poland's neighbours could precipitate a wider conflict. US-led efforts to steer Moscow and Kyiv toward a peace settlement have so far failed to get traction.

The Polish Air Navigation Agency on Thursday announced that Poland was introducing air traffic restrictions in the eastern part of the country.
