Islamic State militants are putting up a desperate fight against advances by US-backed Syrian forces.
A commander with the Syrian Democratic Forces said the extremists have staged a counter-attack from the tiny speck of land they still hold in eastern Syria.
He said the IS offensive began overnight, from the west of a riverside pocket in the Syrian village of Baghouz where the Islamic State group has been making its last stand.
He said that the Kurdish-led forces are repelling the IS counter-attack.
A spokesman for the US-backed forces, Adnan Afrin, said IS militants are putting up a “fierce resistance”, firing mortar shells and rocket-propelled grenades.
