A Kurdish woman, who was adopted by an Iranian family as a child, has returned to Iraq to find her biological parents.

During the Iran-Iraq war a chemical attack on Halabja in north-eastern Iraq killed at least 5,000 people, and many children were taken to Iran for safety and treatment.

Maryam was one of those children and after almost 30 years she returned to find her biological family.

The Our World documentary The Lost Daughter of Halabja is on the News Channel 9 and 10 January at 21:30 GMT.
