What is "gas attack"

Gas Attack is a 2001 drama created and produced by Samantha Kingsley and directed by Kenny Glenaan. The film presents a futuristic fictional scenario in which Kurdish asylum seekers are attacked with biological weapons in a Glasgow suburb and details the results on the community affected, the council team supporting them, the local authorities and emergency services involved in the crisis, the greater public impact and the medical staff that struggle to cope with the influx of victims. The film attracted much controversy, with Glasgow Council considering a ban on the broadcasting of the film, but won three awards for its screenplay, including the British Independent Film Awards.
