The FBI has arrested a 21-year-old air national guardsman in Massachusetts suspected of being responsible for the leak of US classified defence documents that laid bare military secrets and upset Washington's relations with key allies.

Jack Teixeira was arrested at his home in the town of North Dighton by FBI agents.
