BEIRUT – Syrian government forces look set to recover a strategic town that has been in rebel hands since 2014 in a major Russian-backed offensive into the opposition’s last major stronghold.
An organization that monitors the war and a pro-Damascus military source said insurgents had withdrawn from Khan Sheikhoun overnight, though the main insurgent group in the area said rebels still held part of the town and fighting continued.
Capturing Khan Sheikhoun would be an important gain for President Bashar Assad into the northwestern region where his bid to recover “every inch” of Syria has run into complications including Turkish forces on the ground.
Syrian state media, in a broadcast from near the town, reported that government forces had widened their control including by seizing a highway running through Khan Sheikhoun, which was targeted in a sarin poison gas attack in 2017.
The pro-Damascus military source told Reuters the town was under army control after the rebels were caught in a pincer movement and fled.
“There are some pockets and explosive devices, there are a few who refuse to withdraw and want to die,” the source said.
The Syrian Observatory for Human Rights, a British-based war monitoring group, said rebels had withdrawn from their last piece of territory in neighboring Hama province in addition to Khan Sheikhoun, in Idlib.
The most powerful insurgent group in the area, the jihadist Hayat Tahrir al-Sham, denied this and said the battle continued.
In a statement, Hayat Tahrir al-Sham said rebels still held part of Khan Sheikhoun and nearby areas in northern Hama despite what it described as a redeployment in the town after fierce enemy bombardment.
Another rebel alliance, the Turkey-backed National Liberation Front, said bombardment in the northern Hama area had made its forces leave positions that had become difficult to supply and redeploy to others.
Rebel fighters “did not leave an inch of land before making the enemy taste great calamities,” it said.
The Observatory and the pro-Damascus military source said Syrian rebels had pulled back to a Turkish military position in the town of Morek, south of Khan Sheikhoun.
Turkey has established a dozen military positions in the area under agreements with Russia.
One of its main aims is to prevent another refugee influx. Some 3.6 million Syrian refugees already live in Turkey.
The pro-Damascus source said negotiations were under way between Turkey and Russia over the withdrawal of the Turkish position.
But Turkish Foreign Minister Mevlut Cavusoglu said Turkey would not remove the observation post near Morek, which a Turkish convoy was trying to reach on Monday when it came under attack.
After eight years of conflict, Assad has defeated rebels across much of Syria helped by Russia and Iran.
Syrian government forces stepped up military operations against in the northwest in late April.
The offensive has killed hundreds of people and forced hundreds of thousands of others to flee toward the Turkish border.
“A humanitarian disaster, which humanitarian agencies have been warning about for months, is unfolding in Idlib province,” Rehana Zawar, Syria country director for the International Rescue Committee, said in an emailed statement.
“At least 45 schools have been impacted by the violence and 42 attacks on health care have been reported since the upsurge began,” the IRC statement added.
Russia and Syria have said their forces are not targeting civilians and are instead targeting militants.
Russia has military servicemen stationed on the ground in the Idlib region and is following the situation there closely, Interfax news agency cited Foreign Minister Sergei Lavrov as saying on Tuesday. He said any attacks carried out by militants in Idlib’s de-escalation zone would be forcefully suppressed.
Khan Sheikhoun has been in rebel hands since 2014. The opposition’s territorial foothold in neighboring Hama dates back to the earliest days of the civil war.
Syrian state media said the dispatch of a Turkish military convoy into Syria was an act of aggression and it had entered to help insurgents fighting an army advance in Khan Sheikhoun.
The convoy was targeted in an airstrike on Monday after it entered the territory. Rebel sources said the Syrian government had targeted it.
The U.S.-based Union of Medical Care and Relief Organizations (UOSSM), which supports medical facilities in the northwest, says more than 730 civilians have been killed by government or Russian forces since late April.
The U.N. Office for the Coordination of Humanitarian Affairs has said more than 500 civilians have died in hostilities.
