Current fighting pushes Iraqi refugee population past 1 million

Story highlights

  • The number of people fleeing their homes in Iraq nearly doubled overnight, U.N. says
  • 500,000 people have been displaced from the northern city of Mosul
  • 480,000 have left their homes in Anbar province
  • The cities of Irbil and Duhuk are hosting more than 300,000 internally displaced people

The rapid sweep of Islamic militants from Syria into northern Iraq has sent the Middle East into crisis, caused alarm in capitals from Tehran to Washington and forced about half a million people to flee their homes.

The flood of Iraqis trying to escape ISIS fighters doubled the country's displaced population almost overnight. More than 1.1 million people -- nearly one out of 30 -- in Iraq are now displaced.

Ahead of World Refugee Day on Friday, CNN looks at where they came from and where they've gone.
