The main Western - backed militant group in Syria has admitted that it is being overpowered by foreign - backed Takfiri militants.The so-called Syrian National Coalition, which has 15 representatives from the so-called Free Syrian Army (FSA), published a statement on Friday, condemning measures taken by al-Qaeda-linked militants of the Islamic State of Iraq and the Levant (ISIL). Late on Thursday, a ceasefire ended fighting between the FSA and the ISIL militants in the town of Azaz near Syria's border with Turkey. The statement said that the ISIL was “strengthening its positions” in areas under control by the FSA militants. On Wednesday, the Takfiri militants overran the northwestern town of Azaz, a former commercial and industrial hub located five kilometers (two miles) from the border. Syria has been gripped by deadly unrest since 2011. According to reports, the Western powers and their regional allies -- especially Qatar, Saudi Arabia, and Turkey -- are supporting the militants operating inside Syria. In a recent statement, the United Nations High Commissioner for Refugees said the number of Syrian refugees, who have fled the country’s 29-month-long conflict, reached two million. The UN refugee agency also said some 4.2 million people have also been displaced inside Syria since the beginning of the conflict in the Arab country.
