NATO air policing units were put on a higher state of readiness following a near-miss between a Russian fighter jet and a Polish aircraft on patrol for the EU's border agency Frontex on Friday, a NATO official said.
“NATO air policing detachments were put on higher readiness in response to the dangerous behavior of a Russian military plane in the vicinity of a Polish Frontex aircraft over the Black Sea near Romania," the official said on Monday, speaking on condition of anonymity.
The official said NATO "remains vigilant” and referred further questions to Polish authorities.
