Syrian government strikes kill five Turkish soldiers in Idlib

QAMINAS - Syrian regime artillery killed five Turkish soldiers in Idlib Monday, Turkey's defence ministry said, as the number of people displaced by violence in the region neared 700,000 since December.

The barrage also wounded five soldiers in the violence-plagued northwest, prompting the Turkish military to respond by "destroying targets", the defence ministry added.

The exchange was the second in eight days and took place in the area of Taftanaz, which was recently reinforced by Turkey, said the Britain-based Syrian Observatory for Human Rights.

Monday's incident comes a week after earlier regime shelling killed eight Turkish soldiers, prompting a deadly response by the Turkish army.

The clashes are further straining relations between Damascus and Ankara, while also increasing tension between Russia and Turkey -- the conflict's chief foreign protagonists.

Syrian government forces backed by Moscow have pressed a blistering assault against the last major rebel bastion in Syria's northwest for more than two months.

Violence in the provinces of Idlib and Aleppo has displaced 689,000 people, said David Swanson, spokesman for the United Nation's humanitarian coordination office, OCHA.

"The number of people being displaced in this crisis is now spiralling out of control," he said on Monday.

The exodus is one of the largest of the nine-year civil war and risks creating one of the worst humanitarian catastrophes of the conflict.

It has sparked alarm from rebel backer Turkey which already hosts some 3.7 million Syrian refugees and fears another influx.

Turkey's defence ministry said the troops targeted on Monday had been sent "as reinforcement to the region with an aim to prevent clashes in Idlib, ensure our border security, and stop migration and human tragedy".

Turkish reinforcements 

Since Friday, large convoys of vehicles carrying commandos, tanks and howitzer artillery pieces have reinforced 12 Turkish military posts in Idlib installed by Ankara under a 2018 deal with Russia to stave off a regime offensive.

But the agreement has failed to stop the government's advance, with Turkey saying regime forces have surrounded three of its outposts, despite repeated warnings against such a move.

Following the latest attack, Turkish President Recep Tayyip Erdogan and Defence Minister Hulusi Akar immediately met for talks, Turkish broadcaster NTV reported.

Fahrettin Altun, Erdogan's top press aide, wrote on Twitter that "Turkey retaliated against the attack to destroy all enemy targets and (avenge) our fallen troops".

He added: "The war criminal, who ordered today's heinous attack, targeted the entire international community, not just Turkey."

Erdogan has given Damascus until the end of the month to retreat from its outposts, and urged Russia to convince the regime to halt its offensive.

A Russian delegation has been in Ankara for talks on Idlib since Saturday, with further meetings expected on Monday.

The two countries have worked closely together despite supporting opposing sides of the war.
