Islamic State fighters have returned to Kobane after they were chased out of the Northern Syrian city earlier this year by Kurdish fighters and US-led air strikes.
The Syrian Observatory for Human Rights says a number of people have been killed in fierce clashes in the centre of the town which lies on the border with Turkey.
The Observatory says clashes are still ongoing amid heavy casualties.
