Russian Military Flights in Syria Spike, US Commander Reports.

The US has witnessed a "significant spike" in aggressive Russian military flights in Syria this month, according to the commander of US Central Command. Russian ground-attack aircraft fly over US bases loaded with weapons "in an attempt to try and be provocative." The US and Russia have a deconfliction line between the two militaries to ensure operations do not result in a miscalculation or an unintentional escalation. The Russian actions were a means of trying to "renegotiate the deconfliction protocols that they violate every day."
