NATO Secretary General Mark Rutte reacts as he speaks during a press conference at the NATO headquarters, in Brussels, on September 23, 2025, after the alliance held urgent talks about a Russian jet incursion over Estonia last week. Estonia convened emergency consultations under Article 4 of NATO's founding treaty after armed Russian fighter jets violated its airspace for some 12 minutes on September 19, 2025. That incident -- which saw NATO scramble jets -- came just over a week after the alliance shot down Russian drones over Poland and led Warsaw to demand similar talks. (Photo by JOHN THYS / AFP)
