Poland's Prime Minister Donald Tusk: “As you know, very aggressive Russian-Belarusian exercises are starting on Friday, very close to the Polish border. This has its consequences. The purpose of these exercises is, in particular, the Suwałki Corridor (...). We are facing a growing number of provocations from Russia and Belarus. Therefore, we will close the border with Belarus, including railway crossings, due to the ‘Zapad’ exercises at midnight from Thursday to Friday.”
