BEIRUT, Sept 16, (Agencies): They dug trenches around towns, reinforced caves for cover and put up sand bags around their positions. They issued calls to arms, urging young men to join in the defense of Idlib, the Syrian province where opposition fighters expect to make their last stand against Russianand Iranian-backed government troops they have fought for years.This time, it’s “surrender or die.” As the decisive stand for their last stronghold looms, this motley crew of tens of thousands of opposition fighters, including some of the world’s most radical groups, is looking for ways to salvage whatever is possible of an armed rebellion that at one point in the seven-year conflict controlled more than half of the country.In its last chapter, just as it has throughout the long, bloody war, the Syrian rebellion’s fate lies in foreign hands. This time, the splintered and diverse rebels have only Turkey. “The whole world gave up on us, but Turkey will not,” said Capt Nabij al-Mustafa, spokesman for the Turkish-backed umbrella group known as the National Front for Liberation. Idlib, with its 3 million residents and more than 60,000 fighters, is Turkey’s cross to bear. Ankara has appealed to Russia and Iran, its uneasy negotiating partners, for a diplomatic resolution to the ticking bomb. At the same time, it has sent reinforcements of its troops ringing Idlib, a move designed to ward off a ground assault, at least for now.A wide offensive is only likely after a green light from Russia. But delicate diplomatic moves are at work. Moscow is keen on strengthening ties with Turkey, at a time when Ankara’s relations are at their lowest with the United States.Turkey, by calling on the United States and Europe for support seems to be playing on that interest to pressure Russia to accept its proposals for a solution on Idlib that avoids an attack. On Monday, Turkish President Recep Tayyip Erdogan meets for the second time in 10 days with Russia’s Vladimir Putin, this time in Sochi, Russia. “After proving its infl uence in Syria and the Middle East, Russia wants to pull Turkey away from the West much more than achieve a military victory over the armed Syrian opposition,” Mustafa Ellabbad, an expert on Turkish-Arab relations, wrote in Kuwait’s al-Qabas newspaper.The province, the size of Lebanon, has been the beating heart of the rebellion for years. In rebel hands since 2015, it is the largest contiguous territory they controlled. It has access to Turkish borders, securing supply lines for weapons, fighters and aid. For the past two years, Idlib became the shoe-box into which were pushed an estimated 20,000 rebel fighters from around the country, after their losses to government troops and surrender deals negotiated with Russia and Damascus following devastating sieges. Civilians who refused to go back under government rule were also bussed there, nearly doubling the province’s population.Among the estimated 60,000 opposition fighters in Idlib are at least 10,000 radicals affiliated with the al- Qaeda-linked group, Hayat Tahrir al- Sham (Arabic for Levant Liberation Committee). Thousands of foreign fighters, from China, Europe and the Middle East, are the backbone of the radical groups. The Turkish reinforcements are going to 12 observation points that Ankara set up around Idlib last year under a deal with Russia and Iran creating a “de-escalation zone.” The deal also effectively stopped an earlier government advance and set Turkey up as Idlib’s protector. Separately, Turkey has troops stationed in the enclave under its control north and east of Idlib, where it backs Syrian opposition fighters and a civilian administration. It is part of its plan to create a safe area along the border where some of the more than 3 million Syrian refugees it hosts may return.
