Liverpool hospital bomb likely to have been low-end device, says expert

Explosives professor Jackie Akhavan says probably only detonator of improvised bomb went off

An explosives expert has said she believed that the bomb outside Liverpool Women's Hospital was most likely a simple device made either using flash powder from fireworks or ammonium nitrate that malfunctioned.

Prof Jackie Akhavan, an explosive chemistry expert at Cranfield University, said: This looks like a low-end terrorist-type attack, where it's failed to work," having studied CCTV video of the explosion. It looks like a detonator went off, which broke windows in the car, but there was no sign of a blast wave you would get from a full bomb."
