EASTERN SYRIA (CNN) — ISIS has lost its final stronghold in Syria, the Syrian Democratic Forces announced Saturday, bringing an end to the so-called caliphate declared by the terrorist group in 2014.
The coalition of Kurdish and Arab soldiers backed by US, British and French special 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.
Ending weeks of combat, the US-backed Syrian forces raised a yellow flag atop a building in the town as they celebrated the victory over ISIS.
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.
The SDF 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.
Before the offensive started, SDF officials estimated that 1,500 civilians and 500 ISIS fighters remained, but as the assault got under way it became clear that the actual number was much higher. The final phase of the battle was delayed to allow thousands more civilians — along with foreign ISIS supporters — out of of the besieged town.
The militants who mounted the last stand in Baghouz included some of the most battle-hardened and experienced personnel remaining in ISIS, and the wives and children of the fighters were used as human shields.
SDF commanders told CNN that its fighters had faced fierce resistance from the terror group, which slowed the offensive with snipers, improvised explosive devices improvised and heat-seeking missiles. The militants had also dug a network of underground tunnels that allowed them to move from house to house undetected.
