The twin blasts that leaves 3 dead and 170 injured at Boston, USA yesterday were made from ordinary kitchen pressure cookers filled with some nails, ball bearings and sharp objects that are available at any hardware store. The miscreants have used the ordinary “kitchen-type” egg timers to trigger the pressure cooker bombs. They were neither sophisticated nor need expertise to explode the bombs. Hence, the impact is less otherwise it would have killed several people passing on the streets, say officials.

Though the explosives are made from general household items, forensic experts have found letter ‘6L’ on the container of the bomb, which they hopes will give a lead to their investigation. The investigating officers are of the view that the explosive devices were probably hidden inside dark nylon duffel bags or backpacks and left on the street or sidewalk near the finish line.

So far no suspects were arrested and no one or group has claimed responsibility for the blasts. However, Taliban militants have disowned the blast.

According to reports, out of the 170 injured, condition of 17 is very critical. Martin Richard (8), Krystle Campbell(29) of Medford, Massachusetts and a Chinese citizen, were the three, who killed in the bomb blasts.

A truck load of evidences collected from the blast site have been shifted to FBI laboratory in Quantico, Virginia to reconstruct the scene. Edward Davis, the Boston police commissioner has told the media that, they have collected the video footages from the CVC cameras located in and around the blast site. The yellow tapes and metal barriers encompassing the two explosion sites that stretches nearly a mile-long area have kept the people away from the surrounding areas.The city wears a deserted and sick look since yesterday evening.
