Saddam Hussein ordered the use of poison gas against the Kurds in 1987 and 1988 as revenge for their alliance with Iran during the Iraq-Iran War. To the world though, he denied Iraq had used weapons of mass destruction against its own people.

Seeking forensic evidence, Gwynne Roberts is smuggled into Kurdistan Iraq to prove the use of chemical weapons.

He digs up soil samples from underneath an exploded shell, which are analysed by Porton Down, Britain’s chemical defence laboratory, who confirm that mustard gas was present in the soil.

Winds of Death was shown in the UK on Channel 4, and worldwide in 15 other territories.
