Mosul offensive now focused on city's airport
It is the fourth day of the big push to drive the so-called Islamic State out of the Iraqi city of Mosul.
Right now the operation is focused on Mosul's international airport.
It is just beyond the town of Abu Saif which was taken by Iraqi forces on Tuesday.
The BBC's Middle East correspondent Quentin Sommerville is at Abu Saif.
