Nawaf Khalil, a spokesman for Syria's powerful Kurdish Democratic Union Party, says ISIS group militants in Turkey attacked the border crossing point that links the country to Kobani.

The Britain-based Syrian Observatory for Human Rights and Khalil said the offensive began with an armored vehicle suicide attack on the border crossing.

There was no immediate comment from Ankara.

The ISIS group began its Kobani offensive in mid-September. The town later became the focus of airstrikes by the U.S.-led coalition against the militants.

More than 270 airstrikes from a U.S.-led coalition and an American airdrop of weapons can’t stop the ISIS.

The Observatory said the latest fighting has killed eight Kurdish fighters and 17 terrorists.
