BEIRUT – Kurdish-led fighters overran the last village held by the Islamic State group in Syria on Wednesday, confining its once vast cross-border “caliphate” to two small hamlets, a war monitor said.
It is the culmination of a broad offensive launched by the Syrian Democratic Forces last September with U.S.-led coalition support in which they have reduced the jihadis’ last enclave on the north bank of the Euphrates valley near the Iraqi border to a tiny rump.
The capture of the village of Baghouz leaves the few remaining diehard IS fighters holed up in scattered farmhouses among the irrigated fields and orchards on the north bank of the Euphrates River.
“Search operations are continuing in Baghouz to find any IS fighters who are still hiding,” the head of the Britain-based Syrian Observatory for Human Rights, Rami Abdel Rahman, said.
“The SDF will now have to push on into the farmland around Baghouz.”
The Observatory said late on Tuesday that around 4,900 people, mostly women and children but including 470 IS fighters, had fled the jihadis’ fast dwindling enclave in two days.
Of those 3,500 surrendered to the advancing SDF on Tuesday alone.
They were evacuated on dozens of trucks chartered by the SDF.
The fall of Baghouz follows the SDF’s capture of the enclave’s sole town of Hajin and the villages of Al-Shaafa and Sousa in recent weeks.
The new wave of departures means that nearly 27,000 people have left former IS areas since early December, including almost 1,800 jihadis who have surrendered, the Observatory said.
The whereabouts of the ultra-elusive IS supremo Abu Bakr al-Baghdadi, who has made just one public appearance — in Iraq’s then IS-held second city Mosul in 2014 — are unknown.
The U.S.-led coalition declined to be drawn on when it expected its SDF allies to overrun the final sliver of territory still under IS control.
It stressed the operation’s bigger goal was to minimize the continuing threat the jihadis could pose from underground.
“It is difficult to say how much longer, despite the progress,” coalition spokesman Colonel Sean Ryan said.
“We try to stay away from timelines as it is more about degrading the enemy’s capabilities.
“We are seeing a lot of enemy fighters fleeing. The Syrian forces are less than 10 kilometers (six miles) from the Iraqi border but still fighting against a resistance of diehard fighters.”
The remaining jihadis are well within artillery range of Iraqi forces stationed along the border, who are determined to prevent fugitive IS fighters from slipping across.
On Saturday, Iraqi shelling and airstrikes on IS positions in an around Baghouz killed at least 20 jihadis, according to the Observatory.
The coalition has stepped up its own airstrikes against IS since the jihadis killed four Americans and 15 other people in a suicide bombing on a restaurant in the flash point northern town of Manbij on Jan. 16.
The U.S. losses were the biggest since Washington deployed troops in Syria in 2014 in support of the SDF.
Previously it had reported just two combat losses in separate incidents.
The Manbij bombing rekindled controversy triggered by President Donald Trump last month with his surprise announcement of a full withdrawal from Syria.
The U.S. president justified the order with the assertion that the jihadis had now been “largely defeated” in Syria, a claim that the attack threw into renewed question.
It is a far cry from the jihadis’ peak in 2014, when they overran large parts of Syria and neighboring Iraq, and IS proclaimed a “caliphate” in areas under their control.
The gains have come at the cost of heavy losses for the mainly Kurdish fighters of the SDF and despite their sense of betrayal by their U.S. ally after Trump’s withdrawal announcement.
Neighboring Turkey has threatened repeatedly to launch a cross-border operation to crush the Kurdish fighters of the SDF and the autonomous region they have set up in areas of northern and northeastern Syria under their control.
Turkish troops had been held at bay by the intervention of U.S. troops who set up observation posts along the border and mounted joint patrols with Kurdish fighters.
But with those troops gone, the Kurds fear they will be exposed to the full might of the Turkish military.
