France warned on Friday against a repeat of the bloody Syrian battle that devastated Aleppo as the Syrian regime and its allies stepped up air strikes and shelling in the opposition-controlled northwestern Idlib region since late April.
"A new Aleppo must at all cost be prevented in Idlib," French Ambassador Francois Delattre told reporters ahead of the closed-door UN Security Council meeting.
The escalation has raised alarm over a possible all-out assault by Damascus to seize the territory.
Syrian forces backed by Russian air power waged a long battle for Aleppo that ended in late 2016, costing thousands of lives and leaving the historic city in ruins.
"We need to send a very clear message to all those who might be tempted by an escalation in Idlib," Delattre said.
"If it happens, then you will have a humanitarian catastrophe there -- it's written -- and on top of it you will destroy the perspective of a political process that we all want to give a boost to."
Belgium, Germany and Kuwait, three non-permanent council members, requested the urgent meeting after hospitals and schools were hit by strikes. More than 150,000 people have been displaced in one week alone.
The three countries are leading the council's efforts to address the humanitarian crisis in Syria, now in its ninth year of war.
Turkey echoed France's warning with Defense Minister Hulusi Akar saying the Syrian regime needs to halt attacks in Idlib.
“Humanitarian problems grow each day and it is increasingly showing a tendency to turn into a catastrophe,” he said.
Akara also said the attacks pose a threat to the security of Turkey’s observation posts in the northwest, where Turkey carries out patrols.
“We expect Russia to take effective and determined measures to make regime forces stop their attacks on the south of Idlib and immediately return to the borders set by the Astana agreement,” Akara said, referring to the Kazakh capital by its previous name.
On Monday, Russian Deputy Foreign Minister Sergei Vershinin said the operation was a reaction to terrorists in the area, and was being carried out “in coordination with our Turkish partners”, TAS news agency reported.
Since April 29, 12 health facilities including two major hospitals have been hit in northwest Syria, according to the World Health Organization.
About three million people live in Idlib, the last major bastion to remain outside the control of the Syrian regime.
"The situation is dramatic and deteriorating," said German Ambassador Christoph Heusgen, who said civilian infrastructure was being targeted in the bombing campaign.
Diplomats said the meeting was to draw attention to the crisis, but any concrete action would likely be opposed by Russia, a veto-wielding council member.
