Turkish president vows action after Syria shoots down fighter jet
 Turkey’s president said Saturday his country will take “necessary,” but unspecified, action against Syria, a day after Damascus said it had brought down a Turkish military plane near the volatile border between the two countries.

Newly-supplied Russian Buk-M2 anti-air missile used to down Turkish warplane: Since the sophisticated weapons were delivered to the Assad regime in recent weeks, it must be assumed that local missile crews had not finished training in their use and would have had to rely on help from their Russian instructors to fire one.
