Londoners wait for next deadly wave of attacks

IT was just another day in the city of terror. North, south, east and west of its already battered heart, London's Tube network was gripped by panic as explosive devices were discovered in packed carriages.

Above ground, a double-decker bus shook to the sound of a detonation.

Amid the mayhem, London knew it was lucky to emerge without a death toll, but it also now knows the bombers are back and while they only need to be lucky once, the British capital has to be lucky always.
