The Syrian Democratic Forces said it defeated ISIS and fully liberated Baghouz in eastern Syria.
"Syrian Democratic Forces declare total elimination of the so-called caliphate and 100% territorial defeat of ISIS." On this unique day, we commemorate the thousands of martyrs whose efforts made the victory possible, "tweeted Mustafa Bali, head of the SDF press office.
At its peak, ISIS controlled a vast 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
For weeks, US-led coalition airstrikes had pummeled parts of the city while fighters from the Syrian Democratic Forces (SDF) pushed forward on the ground.
Before the offensive began, SDF officials estimated that 1,500 civilians and 500 ISIS fighters remained, but as the assault got under it it became clear that the actual number was much higher. The final phase of the battle was delayed to allow thousands of civilians – along with foreign ISIS supporters – out 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 a fierce resistance from the terror group, which slowed the offensive with snipers, improvised explosive devices improvised and heat-seeking races. The militants had also dug a network of underground tunnels that allowed them to move from house to house undetected.
At the group's height, 7.7 million people were estimated to live under ISIS rule, according to Operation Inherent Resolve (CJTF-OIR), the official name for the coalition fighting ISIS. Many of those people paid taxes, fees and fines to ISIS, which made up a large portion of the group's income.
Despite the loss of territory and funds, July 2018 that ISIS membership in Iraq and Syria was still between 20,000 and 30,000
ISIS may have lost its last sliver of terrain in Syria, but the group is currently waging a fresh guerrilla campaign in far-flung territories of northern Iraq. And its black flag is still flown by affiliates in other corners of the globe, including Nigeria, Libya, Egypt's Sinai Peninsula, Afghanistan and the Philippines.
Joseph Votel, the top American general in the Middle East, warned: "(The Caliphate) still has leaders, still has fighters, it still has facilitators, it still has resources, so our continued military pressure is necessary to continue go after that network. "
The report, the first of its kind since Trump, announced plans to pull all troops from Syria, also says "ISIS remains an active insurgent group in both Iraq and Syria"
"ISIS is regenerating key functions and capabilities more but the absence of sustained [counterterrorism] pressure, ISIS would likely resurge in Syria within six to twelve months and regain limited territory, "the report said.
