The US is building two air bases in northern Syria, Reuters reports based on a Kurdish news site.
Both bases are located in a Kurdish-controlled region; one is to be used for purely military purposes, while the second will have both military and civilian functions.
The runway for a base in the town of Rmeilan is nearly completed and work is stil ongoing at the base near Kobani, on the border with Turkey.
The report claims that dozens of experts and technicians from the US are working on the project.
