"The international coalition has fought ISIS more effectively during the last few days," Nassen told AFP, using an alternative name for IS.
"Before they (IS) were in control of 30 percent of Kobane and now they control less than 20 percent thanks to the international coalition," he said.
Nassen said Kurdish forces were "flushing out" IS fighters from the eastern and southeastern parts of the town on the border with Turkey, calling for more military assistance.
