An activist group and a Kurdish official say Kurdish fighters are making gains against the Islamic State group northeastern Syria, amid airstrikes by the U.S.-led coalition.

Nasser Haj Mansour, a defense official in Syria's Kurdish region, said Saturday the fighters captured the Christian village of Tal Maghas in Hassakeh province, which had been under the control of Islamic State militants. Haj Mansour and the Britain-based Syrian Observatory for Human Rights said the village was taken overnight.

They also said airstrikes by the U.S.-led coalition, the first in the area in days, have targeted IS positions near Tal Tamr village, about 10 kilometers (6 miles) west of Tal Maghas.

Syria's main Kurdish force, the People's Protection Units, or YPG, called Friday for the U.S.-led coalition to attack IS in Hassakeh province.
