WASHINGTON: US Investigators have said that the deadly explosives went off at the Boston Marathon were homemade devices full of nails and metal fragments, possibly packed into kitchen pressure cookers.
The Federal Bureau of Investigation (FBI) said, a day after an attack that left three dead and over 180 injured, that pressure cookers may have been employed by the crude bombs, a common tactic seen in attacks from Afghanistan to France since the 1990s.
“Among items partially recovered are pieces of black nylon, which could be from a backpack, and what appear to be fragments of BBs and nails, possibly contained in a pressure cooker device,” Rick DesLauriers, head of the FBI’s Boston office, said.
Both of the bombs had been placed in a dark colored nylon bag or backpack, he said.
