Nato planes were scrambled in Poland early on Saturday after Russia launched airstrikes targeting neighbouring Ukraine.
'Polish and allied aircraft are operating in our airspace, while ground-based air defence and radar reconnaissance systems have been brought to the highest state of readiness,' Poland's operational command said in a post on X.
Nearly all of Ukraine was under air raid alerts early on Sunday morning following warnings of Russian missile and drone attacks.
Poland scrambled the fighter jets after Moscow launched strikes near its border with Ukraine, but Polish military officials assured the operation was 'preventative and aimed at securing airspace in areas adjacent to the threatened area'.
The operation was launched partly because of a Russian drone incursion into Polish airspace during an attack on Ukraine last week, with the incident forcing Polish and other Nato fighter jets to shoot down Russian drones flying over eastern Poland.
