“A significant threat to our country” has been “eliminated”, Macron said on Twitter, while warning that “the threat remains and the fight against terrorist groups must continue.”

Kurdish-led forces pronounced the death of the Islamic State group's nearly five-year-old “caliphate” on Saturday, after flushing out diehard jihadists from their very last bastion in eastern Syria.

Fighters of the US-backed Syrian Democratic Forces raised their yellow flag in Baghouz, the remote riverside village where diehard jihadists of a variety of nationalities made a desperate, dramatic last stand.

The SDF's victory capped a deadly six-month operation against the final remnants of the caliphate which once stretched across a vast swathe of Iraq and Syria, and held seven million people in its sway.
