Photos: Swedish soldiers join YPG in fight against ISIS

(Photos)- Social media pages loyal to Kurdish People's Protection Units (YPG) have circulated photos for a squad of Swedish soldiers who has joined the Kurdish militia in fighting against the Islamic State (ISIS) northeast Syria.

The Kurdish YPG militia, already a U.S. partner in the fight against Islamic State, has shown grit fighting Islamic State but its potency will likely diminish beyond the Kurdish areas.

A senior Western diplomat told Reuters last month that the significance of Islamic State's recent setbacks should not be exaggerated, but added: "There’s no doubt that the heady days of ISIS are over."
