Ten Iraqi peshmerga fighters entered a northern Syrian border town, crossing over from Turkey on Thursday, the first from among a group of 150 Kurdish troops on their way into the embattled Kobani, activists said. The development followed heavy overnight clashes as Islamic State fighters unsuccessfully tried to capture the border crossing point, the only gateway in and out of the strategic Kurdish town besieged by the militants. Kobani-based activist Musrafa Bani said that 10 Kurdish fighters entered Kobani first and that the rest will follow gradually later in the day because the border crossing point has been targeted by various ISIS fighters.
