Fight to drive IS from Syria bastion Raqa nears end

US-backed fighters say they are nearing the "final week" of their assault to drive the Islamic State group from their one-time Syrian bastion Raqa, as the jihadists' self-described caliphate crumbles.
Losing Raqa would be only the latest in a series of crushing defeats for the extremist group, which once controlled large swathes of territory spanning the border between Syria and Iraq.
Captured by IS in 2014, the northern city was the de facto Syrian capital of the jihadists' self-styled "caliphate" until the US-backed assault by the Syrian Democratic Forces, an alliance of Kurdish and Arab fighters.
The militia has captured around 90 per cent of Raqa since entering the city in June, after months of fighting to encircle it.

They are now advancing on IS-held districts from two fronts in the city's north and east, said commander Rojda Felat, who heads the "Wrath of the Euphrates" campaign.
"If the two fronts meet, we can say we have entered the final week of our campaign to liberate Raqa," Felat told AFP on the western outskirts of Raqa yesterday.

"Within three to four days, we will be able to take the decision to begin the final campaign," she added.
Felat said fighting was still fierce along the front line, with IS using snipers, suicide bombers and reinforced positions in tunnels to hold up the SDF advance.

The jihadists still hold Raqa's national hospital, the nearby football stadium and surrounding residential neighbourhoods, including the infamous Al-Naim roundabout, where IS staged public beheadings and crucifixions.
SDF fighters have surrounded the hospital and were yesterday preparing a fresh push to seize the stadium before moving to Al-Naim, said Ali Sher, a field commander with the Kurdish People's Protection Units (YPG), which make up the bulk of the SDF.
"Then, there will only be the hospital left. At that point, we will call out to them to surrender and if they do not follow these orders, we will have to break down the barriers and enter the hospital," Sher told AFP.

IS is believed to be holding civilians as human shields in the hospital, complicating efforts to capture the position.
Colonel Ryan Dillon, spokesman for the US-led coalition backing the SDF's assault, said IS was using the hospital as a military base and it was "heavily fortified".
He said coalition special forces advisors could accompany the SDF in a push for the facility but there would not be "full, tactical, coalition units assaulting the hospital".
Tens of thousands of civilians have fled Raqa city and the surrounding area since the SDF began its offensive, but many others have remained trapped inside during the heavy fighting.

Laila, 32, escaped yesterday from a building near the stadium.
A mother-of-three, and pregnant with her fourth child, she feared her missing husband had been killed in shelling.
She described utter terror as she sheltered with her children during ferocious air strikes and mortar fire that collapsed buildings around them.
"Those who were still alive were screaming under the rubble but no one dared pull them out because there was so much shelling," she said.
"We lived for three months in the bathroom. My son kept telling me, 'I just want to see the sun, I just want to see the sun.' Today he saw it for the first time.
