Turkey says it's helped rebel forces take back key Syrian town

Turkey-backed Syrian opposition fighters Thursday retook a strategic northwestern town in Syria, opposition activists said, and cut off the key highway linking the capital, Damascus, with the northern city of Aleppo, days after the government reopened it for the first time since 2012.

Despite the loss of Saraqeb, government forces made major gains to the south, taking control of almost the entire southern part of Idlib province with the capture of more than 20 villages Thursday, state media and opposition activists said.

The retaking of Saraqeb, which sits on the M5 highway, is a setback for Syrian President Basharal-Assad's forces who have scored major gains in a weeks-long Russian-backed campaign in the last rebel stronghold in Idlib province. Officials had hailed the reopening of the motorway as a major victory in the nine-year conflict.

The government's military campaign to recapture Idlib, the last opposition-held stronghold in the country, has triggered a humanitarian catastrophe and the war's largest single wave of displacement. According to the United Nations, almost 950,000 civilians have been displaced since early December, and more than 300 have been killed. Most have fled farther north to safer areas near the Turkish border, overwhelming camps already crowded with refugees in cold winter weather.

The Britain-based Syrian Observatory for Human Rights, an opposition war monitoring group, said the opposition fighters seized the town of Saraqeb after intense bombardment by Turkish troops. Turkey and Russia support opposite sides in Syria's brutal civil war, with Ankara backing the opposition and Moscow backing Assad.

From inside Saraqeb, activist Taher al-Omar said the town is now under opposition control. He posted a video with a fighter saying the government forces "ran away like rats."

The Observatory said more than 60 fighters were killed on both sides since Wednesday, adding that later on Thursday, government forces launched a counteroffensive under the cover of Russian airstrikes to try retake the town.

Syrian state media reported intense clashes near Saraqeb, saying insurgents sent suicide car bombs and that Turkish forces bombarded the area. It said a small group of insurgents reached the highway to score a "propaganda stunt," adding that "Syrian troops are dealing with them."

State TV later Thursday confirmed that insurgents have cut the highway and thatfighting is ongoing in the area.

In southern parts of Idlib, government forces captured more than 20 villages since late Wednesday, bringing southern parts of the rebel stronghold under government control, the Observatory said. It saidthat Syrian troops have now besieged another Turkish observation post in an area known as Sheer Maghar.

Russia, Turkey talking, but not progressing

The government-controlled Syrian Central Military Media said government forces marching from northern parts of Hama province met Thursday with forces moving from southern Idlib, bringing wide areas under Syrian army control.

If government forces now turn their march north they can eventually reach another major highway known as the M4 that links Syria's coastal region with the country's west. Assad has vowed to regain control of all parts of Syria.

Backed by Russian air power, Assad's forces have over the past few days captured dozens of villages, including major rebel strongholds, in the last opposition-held area.

The campaign also seized the last segments of the south-north M5 highway. When the government forces first took Saraqeb earlier this month, it marked their capture of the last major rebel-held town along the highway.

In recent weeks, Turkey has sent thousands of troops into Idlib. Clashes between Syrian and Turkish troops have killed 18 Turkish soldiers.

Turkey's Defence Ministry said Thursday two Turkish soldiers were killed in Syria in an air attack in the province the previous day, and that two others were wounded.

Front Burner22:01'No safe haven': The escalating crisis in Idlib, Syria

A humanitarian catastrophe is unfolding in Syria's Idlib province. Nearly one million people have been displaced since a Russian-backed Syrian government offensive began in December, forcing hundreds of thousands of people to flee to ever-shrinking camps along the border with Turkey. Today on Front Burner, we talk to CNN senior correspondent Arwa Damon, who was just in Idlib, about what she saw on the ground. These are families that have been displaced multiple times, she tells Jayme. What makes this time so much more different is that its almost as if there is a sense of finality to it theyre going to reach a point where they cant run anymore.

Turkey responded by targeting Syrian government forces. An air defence missile system, an anti-aircraft gun, three tanks, an ammunition vehicle, an anti-tank weapon and two construction vehicles were destroyed, the ministry said.

Turkish and Russian officials were holding a second day of talks in Ankara on Thursday. Two previous rounds in Ankara and Moscow have not yielded tangible progress.

On Wednesday, Erdogan said he would probably meet Russian President Vladimir Putin in Istanbul next Thursday to discuss Idlib. However, the Kremlin said Putin currently had no plans for such talks on that date.
