Islamic State's black flag has been seen above Kobane for the first time, reports Paul Adams
Islamic State (IS) militants have entered the key Syria-Turkey border town of Kobane and taken control of three districts after street-to-street fighting with Syrian Kurd defenders.
IS fighters entered the eastern districts on Monday, raising their black flag on buildings and hills.
Local officials said about 2,000 civilians fled to the Turkish border.
Taking Kobane, besieged for three weeks, would give IS control of a long stretch of the Syrian-Turkish border.
More than 160,000 Syrians, mainly Kurds, have fled the town.
Earlier a local official in Kobane, Idriss Nassan, told the BBC that the town would "certainly fall soon".
He confirmed IS was now in control of Mistenur, the strategic hill above the town and that there was heavy shelling. Kobane is now besieged on three sides.
'Limited weapons'Karwan Zebari, a representative of the Kurdish regional government in the US, told the BBC it would be catastrophic if IS seized control of the town.
"If this continues, if there's no international aid, military aid arriving for the residents of Kobane and these Kurdish fighters that are fighting in Kobane, it could fall into the hands of IS," he said.
He urged Turkey to take action in support of the residents of Kobane.
"I think Turkey's interests, national security, is at stake here as well. It's important that Turkey steps up and assists these Kurdish fighters in repelling this IS momentum."
Asya Abdullah, a senior Kurdish politician and co-leader of the Democratic Union Party, is in Kobane and told the BBC's Newshour programme that fighting was continuing.
She said: "There is fighting on Kobane's streets now. There are still thousands of civilians in the city and IS is using heavy weapons. If they are not stopped now, there will be a big massacre.
