Tell Brak
The MFS was a part of a YPG-led offensive against Jabhat al-Nusra and the Islamic State of Iraq and the Levant (ISIL), which began on 26 December 2013 in the Tel Hamis area. The YPG and MFS were unable to hold Tell Brak and failed to capture Tel Hamis, and the offensive was called off in early January. Tell Brak was captured on February 23 in a pre-dawn raid by the YPG and the Syriac Military Council.
