Istanbul: A group of 292 Syrians went back to the Syrian town of Jarablus from Turkey on Wednesday, marking the first formal return of civilians since Ankara launched a military incursion two weeks ago to try to secure the border region, a Turkish official said.
Jarablus, which had been held by IS, was the first town captured by Turkey's army and its Syrian rebel allies in an offensive launched on August 24 that aims to sweep away militants and Syrian Kurdish militias from the frontier.
Turkey has said it cleared militants from a 90-km (56-mile) stretch of Syrian territory and has pushed south. It has also said it would support any US initiative to strike IS's stronghold of Raqqa, further to the southeast.
But Turkey's tactics have drawn criticism from its NATO ally the United States and also from Russia, with which it recently patched up ties.
Washington says Turkish attacks on Kurdish-aligned militias damage a US-backed coalition that is fighting IS. Russia, which backs the government in Damascus, said on Wednesday Ankara's push south threatened Syria's sovereignty.
"We call on Ankara to refrain from any steps which can further destabilise the situation in Syria," Russia's Foreign Ministry said in a statement.
Turkish Deputy Prime Minister Nurettin Canikli said Turkey-backed forces may go deeper into Syria after securing a stretch of land along the Turkish border.
Turkey, which hosts three million Syrian refugees, has urged world powers to back plans for a "safe zone" in north Syria to stem the flow of migrants and to allow Syrians to return home.
Although it has failed to win support for the idea, Ankara has pressed on with its offensive to carve out a swathe of territory under the control of the Turkish army and its allies, the Free Syrian Army, allowing some civilians to return home.
"The formal returns have begun today," said a spokesman at the governor's office for the southern Turkish province of Gaziantep, which lies across the border from Jarablus.
He said there were 292 people in the first group of registered returnees, including women, children and the elderly. More would be allowed to return but only gradually, he added.
"Turkey has supported us in every way until now, and has now saved our homeland," said Fatima Mahmud, a mother who was among the group, told the Turkish newspaper Milliyet.
The United Nations has said an area can only be declared a "safe zone" if the protection of civilians can be guaranteed. It has previously cautioned against encouraging returns too soon.
"Currently, conflict lines are too insecure for many of the town's displaced to return safely," the UN humanitarian agency OCHA said in a report last week, referring to Jarablus which had a pre-war population of about 27,500 people.
Further south and west of Jarablus, Turkish forces have continued fighting. The military said late on Tuesday that three Turkish soldiers were killed when two tanks were hit by rockets fired by IS. Four others were wounded, it said.
It said Turkey's rebel allies had taken six more villages, located in IS-held areas, adding to dozens of settlements now under the control of Turkish-backed forces.
Turkish President Tayyip Erdogan said in remarks published on Wednesday by the daily Hurriyet that US President Barack Obama had floated an idea of joint action with Turkey to capture Raqqa, the Syrian city that is IS's de facto capital.
"Obama wants to do some things together concerning Raqqa in particular," Erdogan told reporters on his plane that returned early on Tuesday from a summit of G20 leaders in China, where he met Obama, Russian President Vladimir Putin and other leaders.
Erdogan said he was ready to support such a plan, although he said a specific Turkish role would depend on further talks.
US officials have welcomed Turkish efforts to dislodge IS but voiced concern when Turkish troops engaged fighters aligned with the Kurdish YPG militia, a force Washington sees as a valuable ally in battling militants.
Turkey sees the YPG as an extension of the outlawed Kurdistan Workers Party (PKK), which is waging an insurgency on Turkish soil, seeking autonomy for Turkey's mainly Kurdish southeast region.
