The sister of a British jihadi has said “[I will] kill him myself” if he is revealed as the masked militant in a new Islamic State video showing the murder of five hostages.

Konika Dhar, from north London, said she does not believe her brother is the man in the film, but she conceded the voice sounded “a bit like him”.
