Poland’s prime minister says his country is the closest it’s been to “open conflict” since the second world war after Russian drones entered Polish airspace last night.

Poland’s leader Donald Tusk said the country recorded 19 drones in their airspace last night.

Dr Kenton White from Reading University’s Department of Politics and International Relations told FactCheck he “expect[s] that the 19 reported are those that can be definitely identified. There may be others, but figures tend to be conservative until confirmed definitively.”
