Activists say Kurdish fighters have besieged Islamic State members who have entered the northern Syrian town of Kobani, adding that two days of fighting have left more than 100 dead.

Kobani-based Kurdish activist Mustafa Bali says small groups of jihadis are still in the town and have taken civilians as hostages.

He added that Kurdish fighters are now besieging three locations where IS fighters took up positions.

The Britain-based Syrian Observatory for Human Rights said on Friday that the attack on Kobani and its suburbs left 120 civilians dead.

Bali said more than 100 civilians were killed in Kobani as well as 40 IS fighters whose bodies are still in the streets.

Kobani on Syria's border with Turkey had become a symbol of Kurdish resistance against the Islamic State extremists.
