US-backed fighters in Syria are poised to capture Daesh's last, tiny enclave on the Euphrates, the battle commander said on Saturday, bringing its self-declared caliphate to the brink of total defeat as US President Donald Trump spoke of "100 percent victory".
According to a Reuters report, Jiya Furat said the Syrian Democratic Forces (SDF) had cornered the remaining militants in a neighbourhood of Baghouz village near the Iraqi border, under fire from all sides.
"In the coming few days, in a very short time, we will spread the good tidings to the world of the military end of Daesh," he said. He was speaking after Trump said on Friday there would be "great announcements" about Syria over the next 24 hours.
Trump on Saturday said the caliphate was "ready to fall and that the United States was asking European allies to take back more than 800 Islamic State [Daesh] fighters captured in Syria and put them on trial.
As the SDF advanced under heavy US airstrikes in recent days, a stream of civilians fled the few square miles of hamlets and farmland that remain within Daesh's 'caliphate', along with defeated militants trying to escape unnoticed.
Though Daesh fighters still hold out in a pocket of central Syria's remote desert, and have gone underground as sleeper cells in Iraqi cities, able to launch new attacks, their territorial rule is, for now, almost over.
It ends a project launched from the great mediaeval mosque of Mosul in northern Iraq in 2014, when Abu Bakr al-Baghdadi seized advantage of regional chaos to proclaim himself caliph, suzerain over all Muslim people and land.
He set up a governing system with courts, a currency and flag that at its height stretched from northwest Syria almost to Baghdad, encompassing some two million inhabitants.

But its reign of terror over minorities and other perceived enemies, marked by massacres, sexual slavery and the beheading of hostages, drew a forceful international military response that pushed it steadily back from 2015.
Most of the fighters left in Baghouz are foreigners, the SDF has said, among the thousands drawn by Baghdadi's promise of a new militant utopia straddling the Iraqi-Syrian border and expunging national borders.
All that remains, said Furat, is an encircled pocket some 700 metres square. "Thousands of civilians are still trapped there as human shields," he said.
The UK-based Syrian Observatory for Human Rights said the SDF had taken control of all of Baghouz after the militants there surrendered. SDF officials denied this.
Spokesman Mustafa Bali said the SDF had caught several militants trying to flee among the civilians. Others had handed themselves over.
Their fate, and that of their families, has befuddled foreign governments, with few ready to repatriate citizens who pledged allegiance to a group sworn to their destruction, but who might be hard to legally prosecute. The SDF does not want to hold them indefinitely.
The fate of Baghdadi is also a mystery. He has led the group since 2010, when it was still an underground al-Qaeda offshoot in Iraq.
