The Syrian Democratic Forces said it defeated ISIS and fully liberated Baghouz in eastern Syria.
“Syrian Democratic Forces declare total elimination of so-called caliphate and 100% territorial defeat of ISIS. On this unique day, we commemorate thousands of martyrs whose efforts made the victory possible,” tweeted Mustafa Bali, head of the SDF press office.
At its peak, ISIS controlled a huge stretch of territory stretching from western Syria to the outskirts of the Iraqi capital of Baghdad. But the final battle took place in the past several weeks around the small and otherwise unremarkable Syrian town of Baghouz, on the banks of the Euphrates River.
A coalition of Kurdish and Arab soldiers backed by US, British and French special forces launched the last assault on the ISIS enclave in early February.
For weeks, US-led coalition airstrikes had pummeled parts of the town while fighters from the Syrian Democratic Forces (SDF) pushed forward on the ground.
Though the defeat ends the group’s grip over the jihadist quasi-state straddling Syria and Iraq that it declared in 2014, it remains a threat.
Some of its fighters still hold out in Syria’s remote central desert and in Iraqi cities they have slipped into the shadows, staging sudden shootings or kidnappings and awaiting a chance to rise again.
