CNN —Russian pilots tried to “dogfight” US jets over Syria, according to a spokesman for US Central Command, part of a recent pattern of more aggressive behavior. The attempts have happened in several of the most recent instances of aggressive behavior from Russian pilots, Col. Joe Buccino said. A video released by US Central Command from April 2 shows a Russian SU-35 fighter jet conducting an “unsafe and unprofessional” intercept of a US F-16 fighter jet. That also includes 26 instances in which armed Russian jets flew over US and coalition positions in Syria. Russia subsequently presented state awards to the pilots of the Russian jets.
