Fate of thousands of Iraqis unknown

Thousands of Iraqis have gone missing since the US-led invasion seven years ago.

It is thought that many disappeared during the sectarian bloodshed and a number were rounded up in military operations.

But as the United States winds down its presence in the country, many families fear they will never find out what really happened to those who disappeared.
