A 500 kg British aerial bomb dug up on a construction site in Sarajevo A 500 kg aerial bomb, dropped during the Second World War by the British Air Force, is dug up at a construction site in Sarajevo. This bomb of "very devastating power", according to experts, was defused shortly afterwards on site and will be transported overnight to be destroyed in the coming days. This measure prevented the evacuation of 15,000 to 20,000 people who were in the potential blast zone around the commercial construction site. IMAGES AND SOUNDBITES
