London: Mourning the worst possible suicide attack on the British soil after the turn of the Century, Prime Minister David Cameron and London Mayor Boris Johnson were among those who laid wreaths in Hyde Park. On 7 July 2005, three explosions took place on the Underground – 26 people died in a bombing at Russell Square on the Piccadilly line; while on the Circle line six died in an explosion at Edgware Road, and seven lost their lives at Aldgate. More than 700 people were also injured in the attacks.
Almost an hour later, a fourth device was set off on a number 30 double-decker bus in Tavistock Square, killing 13 people.A service will take place at St Paul’s Cathedral later, attended by survivors and families of those who died. A minute’s silence will be held during the service and on London’s transport network at 11:30 BST.
