As Syrian President Bashar Assad’s fight against Islamic State draws to a close, violence has exploded in other areas, threatening an even broader confrontation among regional and world powers.
The airman reportedly is slain on the ground in an exchange of gunfire with militants trying to capture him. A British-based group has confirmed his death.
