A leader linked to Al-Qaeda has been released by Kurdish forces in the northern Syrian border region, Reuters reported activists as saying.
A ceasefire between the Islamic State of Iraq and Shama (ISIS), also known as Abu Musaab, and Syrian Kurds has equally resulted in hundreds of kidnapped Kurds being released.
Tensions between the groups have mounted as Islamists try to gain control of rebel zones in the north, whereas Syrian Kurds wish to establish their sovereignty.
