In cities and towns across Syrias last opposition-held province, Idlib, residents poured into the streets on Friday to demonstrate against Bashar Assads regime in defiance of an expected offensive to retake the territory. In the provincial capital, Idlib city, and in towns including Kafranbel, Dana, Azaz, Maaret al-Numan and al-Bab, demonstrators filled the streets after noon prayers and chanted against Assad, raising the tri-color green, white and black flag that has become the banner of Syrias 2011 uprising, activists said. "The rebels are our hope; Turks are our brothers; the terrorists are Bashar, Hezbollah and Russia," read a banner carried by residents in the village of Kneiset Bani Omar, referring to Turkey which backs the opposition, and Lebanons “Hezbollah” and Russia that have joined the war along with Assads forces. "There will be no solution in Syria without Assads fall," read another banner carried in the northern village of Mhambel, reported The Associated Press. The demonstrations were reported on the activist-run sites Aleppo Media Center, Orient News, and other social media pages. Fridays have become the customary day for protests throughout the Arab world since the 2011 uprisings that swept through the region. Wissam Zarqa, a university teacher in Idlib, said demonstrators were flying the tri-color flag to rebut the regime line that Idlib is dominated by the al-Qaida linked Hayat Tahrir al-Sham group. The province, population 3 million, is now the final shelter for close to 1.5 million displaced Syrians that fled fighting in other parts of Syria. Many say they will not return to regime-ruled areas. Regime and Russian forces bombed towns and villages in the province earlier this week, killing more than a dozen civilians and damaging two hospitals. But the strikes eased on Wednesday amid talks between the oppositions main regional sponsor Turkey, and Russia and Turkey. Turkish President Recep Tayyip Erdogan and his Russian counterpart Vladimir Putin are slated to meet Monday, said Turkish Foreign Minister Mevlut Cavusoglu. "We will continue our efforts with Iran and with Russia. ... (and) on international platforms as well," said Cavusoglu in comments carried live on Turkish television. Turkish media said the two leaders would meet in the Russian city of Sochi. Turkey has warned strongly against military action, saying it would trigger a humanitarian catastrophe. Its military and defense chiefs visited border areas on Friday to inspect troop reinforcements sent to its Hatay and Gaziantep provinces. Turkey has 12 military posts inside Idlib province, and activists reported on Thursday that Turkish reinforcements crossed over into Syria to fortify the installations. The United Nations said that in the first 12 days of September, over 30,000 people have been internally displaced by an intense aerial bombing campaign. Most of the displaced headed toward the border with Turkey, according to the UN Office for the Coordination of Humanitarian Affairs, packing already overcrowded camps there. The UNs World Food Program said it, alongside partners, were already delivering monthly food rations for nearly 600,000 people. It said it was prepared to deliver emergency food assistance for up to 1 million people. Save The Children said in a statement that it will continue to support extensive humanitarian programs through Syrian partner organizations in the countrys northwest. It added that this includes running primary healthcare clinics and a maternity hospital, vaccination and food security programs, supporting a network of schools and carrying out child protection work. "One million children are trapped in Idlib facing what could be the greatest humanitarian catastrophe in the long and bloody history of Syrias seven-year war," said Syria Response Advocacy Manager Caroline Anning.
