Deadly clashes between Syrian pro-government fighters and Kurdish forces raged on Wednesday in the northeastern city of Qamishli, an AFP reporter at the scene said.
Loud blasts from rocket fire and heavy machineguns could be heard throughout the city into the evening as warplanes screeched above, the reporter said.
Qamishli is under the shared control of the Syrian regime and Kurdish authorities, who have declared zones of "autonomous administration" across parts of north and northeast Syria.
The clashes broke out between government forces and the local Kurdish police force, known as the Asayish, at a checkpoint earlier on Wednesday, a Kurdish security source told AFP.
