Fighting occurred between jihadist opposition groups in northwest Syria on Monday, highlighting the fractious differences that remain among rebel forces in Syria.
Following the seizure of Aleppo in December 2016 by Assad government forces, armed opposition groups in northwest Syria have begun to battle over remaining territory and resources.
As Assad regime troops re-consolidate following their victory, opposition forces in the country must contend with infighting and a series of successful foreign interventions.
The Russian military campaign to support Assad continues, and is still largely focused on removing moderate opposition to the Assad regime. Notably, Russian military action against the Islamic State, particularly in its stronghold of Raqqa, has paled in comparison to its actions against moderate rebel groups; the only forces capable of assuming power in Syria should the Assad regime actually fall.
