U.S.-backed fighters close in on last ISIS-held village in Syria

U.S.-backed Syrian forces captured 41 positions held by militants with the group Islamic State in Iraq and Syria (ISIS)and destroyed their fortifications in the last tiny pocket they hold in eastern Syria amid fierce fighting, a spokesperson said Sunday.

Mustafa Bali said the Kurdish-led Syrian Democratic Forces made the advances overnight and on Sunday, hours after they launched a final push to clear the area ofISIS militants on Saturday night.

The final battle to clear the village of Baghouz is now playing out after 20,000 civilians were evacuated from the areain the eastern province of Deir-el-Zour over the past few weeks.

Bali said heavy fighting was going on inside Baghouz on Sunday, adding that an ISIS counterattack was foiled early in the day. He did not say how long the battle was expected to last.

U.S.-led coalition warplanes are giving cover to advancing SDF fighters.

U.S. President Donald Trump predicted Wednesday that ISISwill lose by next week all the territory it once controlled in Iraq and Syria.

That would mark the end of a four-year global war to end the extremist group's territorial hold over large parts of Syria and Iraq, where the group established its self-proclaimed "caliphate" in 2014.

U.S. officials have said in recent weeks that ISIS has lost 99.5 per cent of its territory and is holding onto fewer than fivesquare kilometres in Syria, where the bulk of the fighters are concentrated.

But activists and residents say ISISstill has sleeper cells in Syria and Iraq, and is laying the groundwork for an insurgency. The U.S. military has warned the group could stage a comeback ifmilitary and counterterrorism pressure is eased.
