BEIRUT - Kurdish forces blocked a road Islamic State militants use to resupply their forces in a Syrian town on the Turkish border, a town official and a monitoring group said on Wednesday, the first major gain against the jihadists after weeks of violence.Iraqi-Kurdish peshmerga forces crossed into Kobani on Oct. 31 to help the besieged Kurdish YPG and YPJ fighters in the town. The combined forces have now cut off the road which leads south east to the village of Hilnij, the sources said.Despite having limited strategic significance, the battle in Kobani, also known as Ayn al-Arab, has become a powerful symbol in the fight against Islamic State. The hardline Sunni Muslim group has captured large expanses of Iraq and Syria and declared an Islamic "caliphate".Idris Nassan, a local official in Kobani, said by telephone that anti-IS forces had taken the strategic hill of Mistanour and the road which runs along the side of the hill."ISIS was using this road for ammunition and fighters," he said, using a former name for Islamic State. He added that peshmerga forces had been focusing artillery strikes on IS positions on the outskirts of Kobani like Mistanour over the past week, to halt IS shelling on the town.
