Kurdish activist Mustafa Bali, the Britain-based Syrian Observatory for Human Rights and Kurdish official Idris Naasan put at 40-50 the number of elite IS fighters killed in the two days of fighting since the militants sneaked into the town of Kobani before dawn on Thursday.
Clashes, however, continued to the south and west of the predominantly Kurdish town on the Turkish border on Saturday, they said, although the fighting in the south quietened down by nightfall.
