ANKARA/BEIRUT (Reuters) - Turkey said on Wednesday it will press its military offensive in Syria until Islamic State is driven from the town of al-Bab, despite a warning from forces allied to Syrian President Bashar al-Assad and a helicopter attack on the rebels it backs.
Turkey's incursion into Syria, launched two months ago to drive Islamic State militants from its border and prevent Kurdish fighters from gaining ground in their wake, has complicated an already messy battlefield in northern Syria.
