The man who carried out Saturday's stabbing attack at a London underground station had images and flags of the Islamic State (ISIS) group on his mobile phone, British prosecutors say. Muhyadin Mire, 29, appeared at Westminster Magistrates' Court on Monday after being charged with the attempted murder of a 56-year-old man at the Leytonstone tube station in northeast London. Mire was remanded into custody and will make his next court appearance at the Old Bailey on Friday.
