A Russian Sukhoi Su-35 fighter has come dangerously close to a Polish Frontex aircraft. A Russian fighter jet flew several times at a Polish patrol plane in such a way that it almost crashed.

The Polish plane has been stationed in Romania since April 19 and is scheduled to remain there until May 17. The incident occurred "in international airspace over the Black Sea", about 60 kilometers east of Romanian airspace. Romanian and Spanish planes were then put on "pre-alert" by NATO.
