The apparently coordinated explosions were aimed at the London transportation system, at a time of day when upwards of three-million men and women are making their way to work. And the British government had no doubt who was to blame, saying a band of terrorists, probably from Osama bin Laden's al-Qaida organization. Prime Minister Tony Blair, in a nationwide television address within hours of the explosions, said "It is reasonably clear that there have been a series of terrorist attacks" in downtown London, an outrage that he described as "barbaric." Police say residue from explosives have been found at two of the blast sites, and a former anti-terrorist squad chief, John Stalker, says the attacks bear all the hallmarks of an al-Qaida operation. A previously unheard of terrorist group calling itself the "Secret Organization: al-Qaida in Europe" claimed responsibility for the bloodshed. The death and destruction brought carnage and chaos to the heart of one of the world's busiest capitals. A series of explosions at underground rail stations brought that city's entire system to a standstill for hours. Eyewitnesses reported seeing bodies piled in the wreckage of one train. Some commuters fled one station and climbed aboard a double-decker bus, only to be trapped when a massive explosion blew the vehicle apart, ripping off its roof. Eyewitnesses reported numerous deaths in the bus blast. We spoke to two Londoners Mushfeqa Sobhani and Ashraf Chowdhury who described the carnage and the situation which practically paralized London.as very serious.In another report it was said that when India was trying to recover from the shock of a blast in Ayoddha , people of India as well as Kolkata were shocked by the news of blasts in Kolkata. In their reaction to VOA Bangla Service , one person said that it is the responsibilty of the Indians too to try and prevent any kind of terrorist activities. Another person mentioned that she feels concerned about the terrorist activies and the whole world should act against terrorism. People of the world should not be divided by politics , they should be united for peace. The whole world would look forward to our actions for peace and , therefore, against terroriism.
