More than 100 combatants were killed over the last two days in northern Syria in fighting between Turkish-backed groups and Syrian Kurdish forces, a war monitor said on Sunday.Turkish-backed factions in northern Syria resumed their fight with the SDF at the same time as Islamist-led rebels were launching an offensive on November 27 that overthrew Syrian president Bashar al-Assad just 11 days later.

Turkey said Monday that it was "only a matter of time" before Syrian Kurdish fighters -- seen by the West as essential in the fight against Islamic State jihadists -- will be wiped out.
