The World Health Organization (WHO) is warning that it may have to shut down its network of 77 clinics serving people who fled their homes to escape Islamic State.

Earlier in June, the UN warned it may be forced to reduce more than half of its critical aid operations for those affected by conflict in Iraq.

The UN has appealed for nearly $500m (£325; €443) to cover the immediate needs of 5.6m Iraqis for the next six months.
