A Russian presidential plane carrying journalists was chased across Swiss skies by fighter planes amid mounting tensions between Vladimir Putin and the rest of Europe.
One of the passengers on board the Russian plane, which was headed to Peru, took a video showing the military jet flying by their side, clearly carrying Swiss markings.
Andrey Kolesnikov, editor-in-chief of the magazine Russian Pioneer, wrote on Facebook: 'We're flying above Switzerland. At some point, the plane with the delegation and the journalists is being blocked from three sides by three fighter jets.'
Kolesnikov said the aircraft were so close he could see the faces of the Swiss pilots, and there could have potentially been a crash if they had come much closer.
Despite fears the Russian plane would be forced to make an impromptu landing, the Swiss jets pulled away once it reached the border.
