The United Kingdom is holding the largest-ever disaster rehearsal in Europe.
According to Dailymail, the scenario involves a tower block collapsing on to the bustling Waterloo Tube station, which has been partially built in a disused power station in Kent.
Some 2,000 blood-covered volunteers will act as victims, with fake sliced limbs and open wounds recreating the blood and gore of such a large scale disaster.
Police, firefighters and paramedics together with more than 70 partner agencies will participate in the four-day drill.
