Tension returns to the already unstable relationship between the Free Syrian Army (FSA) and the Kurdish Popular Protection Units in the countryside of Aleppo, following attempts by the FSA to raid Kurdish-controlled villages in the Afrin region.
The clashes in the Afrin region – between units of the Muslim Brotherhood's Tawhid Brigade and Islamist and Kurdish groups supported by Ankara – resulted in the displacement of some villagers and the closure of the Afrin-Aleppo road.
Kurdish sources confirmed to Al-Akhbar that 14 members of the opposition units and two Kurdish fighters were killed over the weekend. The Syrian Observatory for Human Rights said the clashes caused the death of 11 rebel fighters and the injury of more than 20.
