Fireballs and black smoke billow from final IS holdout in Syria

The rattle of guns, bomb blasts and black smoke -- a deluge of fire is being unleashed on the Islamic State's last Syrian stronghold by Kurdish-led and international forces."Watch out, it's coming!" Kurdish commander Hagit Qamishlo shouts to AFP journalists, from the terrace of a house that overlooks the battlefield some 800 metres away."Well played! That was a jihadist sniper position", Qamishlo relays into his walkie talkie.
