Jihadist fighters are defending the last dreg of the Islamic State group’s “caliphate” with ISIS members holed up in half a square kilometre of a village in eastern Syria.

US President Donald Trump said the fall of the IS proto-state would be announced on Saturday, but a top Syrian commander said his forces had slowed down their advance to protect civilians.

The jihadists declared a “caliphate” in large parts of Syria and neighbouring Iraq in 2014, but have since lost all of it but the tiny patch in eastern Syria near the border with Iraq.

Hundreds of metres from the frontline in the village of Baghouz, an AFP reporter heard artillery shelling and two air strikes on the jihadist holdout.

Huge craters had been blown into the ground, and the road was lined with destroyed buildings and the skeletons of burnt-out cars.

“IS is besieged in a neighbourhood that is estimated to be 700 metres long and 700 metres wide” in the village, said Syrian Democratic Forces (SDF) commander Jia Furat.

“Baghouz is within our firing range but we are moving cautiously considering there are civilians still trapped there as human shields,” said Furat, the overall commander for the operation.

“In a very short time, not longer than a few days, we will officially announce the end of IS’s existence,” he told reporters at the Omar oilfield turned SDF base.

Thousands of people have flooded out of Baghouz over the past week — mostly women and children related to IS fighters, but also suspected jihadists.

But SDF spokesman said there were “still civilians inside in large numbers”.

“We weren’t expecting this number … This is why it’s been delayed,” SDF spokesman Adnan Afrin told AFP.

Mr Trump at around 1600 GMT on Friday said announcements over “the eradication of the caliphate” would be made “over the next 24 hours”.

On Saturday, US-led coalition spokesman Colonel Sean Ryan acknowledged that the timeline had slipped because of the presence of civilians inside.

“There has been lapses as we continue to see hundreds of civilians still attempting to flee to safety,” he said.

‘HUNT DOWN’ ISIS REMNANTS
Beyond Baghouz, ISIS still has thousands of fighters and sleeper cells scattered across several countries.

In Syria, it retains a presence in the vast Badia desert, and has claimed deadly attacks in SDF-held territory.

The US Department of Defence has warned that without sustained counter-terrorism pressure, IS could resurge within months.

US Vice President Mike Pence vowed on Saturday at a security conference in the German city of Munich that Washington would continue to fight ISIS remnants even after a military pullout.

“The United States will continue to work with all our allies to hunt down the remnants of ISIS wherever and whenever they rear their ugly heads,” Mr Pence said.

German Chancellor Angela Merkel warned in Munich that a US pullout risks allowing regimen allies Russia and Iran to boost their role in Syria.

A US withdrawal risks leaving Syria’s Kurds exposed to a long-threatened attack by neighbouring Turkey, who views Kurdish fighters as “terrorists”.

To prevent this, they have scrambled to seek a new ally in the Damascus government after spending most of Syria’s civil war working towards self-rule.

Eight years into a war that has killed more than 360,000 people, President Bashar al-Assad’s government controls nearly two-thirds of the country.
