Syria war: Russian helicopter shot down, killing five on board

An alliance of forces, including hardline jihadist factions, is the dominant power in Idlib.
Jabhat Fateh al-Sham - formerly known as Jabhat al-Nusra - is among those active in the province, and so-called Islamic State has vowed to carry out jihad against Russian forces.
The helicopter was carrying three crew and two officers.
Pictures on social media, purportedly of the latest Russian helicopter downing, showed burning wreckage and bodies, with armed men milling around.
Footage showed at least one body being dragged away. Another is seen apparently being trampled on.
