Jihadists from Isis (Islamic State) are preparing a last stand in a key border post between Syria and Turkey, threatening to turn it into another Kobane, the town virtually destroyed in fighting last year.
Kurdish forces attacking Isis across northern Syria were within 3km of the Isis-held town of Tal Abyad, which is the gateway from Turkey to the jihadists' de facto capital of Raqqa, monitors and local residents said.
Thousands of residents were fleeing the fighting, swarming the crossing point which the Turks eventually opened yesterday.
Earlier they had kept it shut, while Isis fighters had been seen trying to force people back to their homes, presumably to serve as human shields against coalition bombing.
