Government helicopters have dropped leaflets over towns in Idlib's eastern countryside urging people to surrender
Saraqeb (Syria) (AFP) - Syrian regime forces shelled rebel and jihadist positions in the northwestern province of Idlib on Thursday and dropped leaflets urging people to surrender.
The province is the largest chunk of territory still in rebel hands, and President Bashar al-Assad has warned it would be his next priority.
The United Nations, for its part, appealed Thursday for talks to avert "a civilian bloodbath" in Idlib, on the border with Turkey.
"The war cannot be allowed to go to Idlib," the head of the United Nations humanitarian taskforce for Syria, Jan Egeland, told reporters in Geneva.
Egeland said he remained "hopeful" that diplomatic efforts could avert a major ground offensive that would force hundreds of thousands to flee.
"It is bad now" in Idlib, Egeland said. "It could be 100 times worse."
The warning came as government helicopters dropped leaflets over towns in Idlib's eastern countryside urging people to surrender, an AFP correspondent said.
"The war is nearing an end... We are calling on you to join the local reconciliations, as many of our people in Syria did," said the leaflets, which were stamped with the military's seal.
Such surrender deals are often negotiated by regime ally Russia.
They typically see rebels hand over territory to government troops in exchange for a halt to shelling, the return of state institutions, and a chance to either join regime forces or be bussed out of the area.
"The fate of your family, children and future depend on your decision," warned the leaflets.
Heavy artillery and rocket fire on Thursday morning slammed into territory around Jisr al-Shughur, a key town in the southwestern part of the province, according to the Syrian Observatory for Human Rights.
"The shelling is in preparation for a possible regime assault on that area," Observatory head Rami Abdel Rahman said, referring to Jisr al-Shughur.
But "the fate of remaining areas in the province depend on any deal" between key powerbrokers Russia and Turkey, he said.
Jisr al-Shughur is near the administrative borders with Latakia and Hama provinces.
"Regime reinforcements including equipment, soldiers, vehicles and ammunition have been arriving since Tuesday," he told AFP.
They were arriving in three regime-held areas: Latakia province just west of Jisr al-Shughur, in the Sahl al-Ghab plain to the south in Hama province, and in a sliver of the province's southeast that is already in government hands.
Al-Watan newspaper, which is close to the government, also reported on Thursday that army troops had bombed rebel and jihadist positions in the area.
Idlib, which has escaped regime control since 2015, lies along the border with Turkey but is otherwise nearly completely surrounded by government-held territory.
Around 60 percent of it is now held by Hayat Tahrir al-Sham (HTS), which is led by Al-Qaeda's former Syria affiliate, while rival opposition factions also control territory.
Syrian troops have recaptured key swathes of the country in recent months with Russia's help.
- Dozens arrested -
Apparently fearing a surrender deal for Idlib, HTS has been arresting dozens of figures in the province that have been go-betweens with the regime.
Early Thursday, the group detained several such figures from villages in Idlib's southeast, calling them "chiefs of treason", according to an HTS-linked media agency.
The Britain-based Observatory, which relies on a network of sources inside Syria, said it had documented more than 100 such arrests by HTS and rival forces this week alone.
Idlib province is home to around 2.5 million people, including rebels and civilians transferred en masse from other territory that fell to Syrian troops after intense assaults.
It was designated last year as one of four "de-escalation" zones where violence was supposed to be reduced ahead of a nationwide ceasefire.
It is the only such zone left, after Assad's troops in recent months recaptured the other three with a blend of military assaults and "reconciliation" deals.
