Further details about the incident weren't immediately available. It is one of the latest incidents in what NATO has said is an increase in Russian military flights near alliance members' territorym Censor.NET reports citing CNN.
In November, NATO said its members' jets had been scrambled more than 400 times in 2014 to intercept Russian military flights close to members' territories -- a 50% increase over the previous year. The increase harkens back to the days of the Cold War, NATO Secretary General Jens Stoltenberg said November 20 during a visit to NATO member Estonia.
UK jets intercepted more than 100 Russian aircraft last year, according to the British Defence Ministry.
