According to the ministry, Russia's radars detected an air target approaching the state border over the Pacific Ocean.
"A MiG-31 fighter took off from an airfield in the Kamchatka Region to identify and escort it. The fighter crew identified the air target as an RC-135 strategic reconnaissance aircraft of the US air force. After the foreign military aircraft turned away from the Russian Federation's state border, the Russian fighter returned safely to its home airfield", the defence ministry told reporters, stressing that "no violation of the Russian Federation's state border was allowed".
