London Blasts: An Anti-War Response - Coordinated Terrorist Attack Hits London on 7th July 2005. The 7 July 2005 London bombings (referred to often as 7/7) were a series of coordinated suicide attacks upon the United Kingdom, targeting Londoners using the public transport system during the morning rush hour. During that morning, four homegrown militants detonated four bombs, three on London Underground trains in quick succession, a fourth bomb exploding an hour later in a double-decker bus in Tavistock Square. Fifty-six people, including four bombers, were killed by the attacks, and about 700 were injured. The explosions were caused by homemade, organic peroxide-based devices packed into rucksacks.

A series of four explosions struck London's public transportation system Thursday in what Prime Minister Tony Blair called a coordinated series of "barbaric" terrorist attacks, most likely timed to coincide with the opening of the G-8 summit in Scotland. "This is a very sad day for the British people," Blair said in an afternoon address from 10 Downing Street. "We will not be terrorized."
