It was London’s deadliest peacetime attack – no warning was given. The British capital is now on high alert.At least 37 were killed and more than 700 were wounded as a series of bomb attacks targeted commuters on Thursday morning. It’s believed the death toll could rise – 45 people are in a critical condition. Just a glimpse of the terror is seen on mobile phone images – people fled smoke-filled carriages underground. The blasts went off within an hour of each other on three tube trains and one bus. The bus that was targetted was near Russell Square near the British Museum. It was ripped apart. A group calling itself the Secret Organization of Al-Quaida in Europe said it carried out the attacks in retaliation for Britain’s involvement in Iraq and Afghanistan. The scenes in London came just hours after Londoners celebrated their selection as hosts of the 2012 Olympic Games and with the G8 summit in Scotland underway. This was the terrorist attack London had long feared.
