MOSCOW, April 7 (Xinhua) -- A Russian MiG-31 fighter escorted a Norwegian reconnaissance plane above the Barents Sea on Wednesday, the Russian Defense Ministry said.
Russian airspace control systems detected an air target approaching the Russian border and a MiG-31 of the Northern Fleet took off in response, the ministry said.
The crew of the Russian plane identified the air target as a Norwegian military aircraft Falcon-20 for electronic reconnaissance and warfare.
After the Norwegian aircraft flew away from the Russian border, the MiG-31 returned safely to its home airfield.
The flight of the Russian fighter strictly complied with international rules for the use of airspace, it added.
