In this photo taken on Saturday, Oct. 3, 2015, Russian SU-24M jet fighter armed with laser guided bombs takes off from a runaway at Hmeimim airbase in Syria.

The air forces of multiple countries are on the attack, often at cross purposes in Syria’s civil war, sometimes without coordination and now, it seems, at risk of unintended conflict.
