Mosul battle: Escaping civilians facing 'dire conditions'

Iraqi civilians are said to be enduring dire conditions after fleeing the Mosul area as the army attempts to retake the city from so-called Islamic State (IS).
Some 5,000 people have crossed the border into Syria in the last 10 days, the aid agency Save the Children says.
They have arrived at the al-Hol refugee camp where conditions are already reported to be filthy and overcrowded.
Up to 1.5 million civilians are thought to still be in Mosul, and up to 5,000 IS fighters.
The commander of the US-led coalition against IS, Gary Volesky, said the militant group's leaders were fleeing the city, but did not say who was leaving, or where they were heading.
The whereabouts of IS leader Abu Bakr al-Baghdadi are unknown. Some reports say he is in Mosul; others say he has fled.
