Three packages sent to Heathrow, London City Airport and Waterloo station were bombs, police have confirmed. Areas of the three main transport hubs were sealed off today after suspicious packages were sent to each in actions anti-terror police believed are linked. Pictures shared online show the crude devices packed in envelopes reading simply 'Heathrow' and 'London Waterloo'. Part of the bag sent to the offices of Heathrow Airport was burnt away when it went off, causing a small fire which saw the building evacuated.
