Turkey Will Strike Regime Forces Anywhere in Syria, Warns Erdogan after Flareup

Violence has flared in Idlib, in northwest Syria and bordering Turkey, in recent weeks as regime forces backed by Russia and Iran have made gains in their campaign to eliminate the last opposition bastion in Syria's nine-year-old war.

Turkey, which is allied with some opposition groups opposed to Assad, mounted a counter-attack on Tuesday after 13 Turkish soldiers were killed by Syrian shelling in Idlib in the last 10 days.

"If there is the smallest injury to our soldiers on the observation posts or other places, I am declaring from here that we will hit the regime forces everywhere from today, regardless of Idlib's borders or the lines of the Sochi agreement," Erdogan said, referring to a 2018 ceasefire accord.

"We will do this by any means necessary, by air or ground, without hesitating, without allowing for any stalling," he told members of his AK Party in Ankara. Russia, which has an air base in Syria, has controlled Idlib's air space for several years.

Turkey has set up 12 observation posts in Idlib as part of an agreement with Russia and Iran to establish what is termed a de-escalation zone.

This month it has poured some 5,000 troops and convoys of military vehicles across the border into Idlib, including tanks, armored personnel carriers and radar equipment to bolster its existing military positions.

The Turkish military casualties have sparked some of the most serious confrontations between Ankara and Damascus in the war, which has killed hundreds of thousands of people and made millions refugees, including 3.7 million Syrians in Turkey.

The fighting - which has driven nearly 700,000 people from their homes in the last 10 weeks - has also strained ties between Moscow and Ankara, which says it cannot handle another wave of refugees.

TASS news agency quoted the Kremlin as saying that Russian President Vladimir Putin and Erdogan agreed in a phone call the sides would continue contacts on Syria. Erdogan said he discussed with Putin the "damage the (Syrian) regime and even Russia inflicted" on Turkish soldiers there.

Erdogan said Russian and regime attacks have targeted not terrorists but civilians.

"Russian forces and Iran backed militias are constantly attacking the civilian people, carrying out massacres, spilling blood," he said, according to Reuters.

In the 2017 and 2018 Astana and Sochi accords, as well as in a ceasefire deal last month, Turkey and Russia agreed to work towards de-escalating the fighting in Idlib and creating a demilitarized zone.

The US envoy for Syria, James Jeffrey, is meeting senior Turkish officials in Ankara on Wednesday. He said on Tuesday that "our NATO ally Turkey is facing a threat from Assad's regime and Russia," adding Washington could offer support.

Turkish-backed opposition groups have mobilized to push Damascus’ forces out of Idlib, Erdogan said, adding they must remain disciplined.

"We have given the message that we will act without compromise to those from the opposition groups who act in an undisciplined way and give the regime an excuse to attack," he said.

Turkish artillery has been supporting the opposition factions as they battle to hold on to areas of Idlib. Turkey said on Tuesday 51 Syrian soldiers were killed as fighters struck back against regime forces, who had made gains in their campaign.

Much of the fighting in the past week has focused on the M5 highway, linking the former economic hub of Aleppo to the capital Damascus to the south.

Russia has officers on the ground advising the regime on the campaign as well as some ground forces, and Russian warplanes have carried out numerous air strikes.
