Rescue teams search for construction workers buried in rubble after building collapses

Part of an apartment building under reconstruction in the centre of Prague collapsed on Friday, with three floors caving in on an inner courtyard. Rescue crews – with the help of sniffer dogs – are trying to find four construction workers thought to be buried in the rubble. All four were working on the highest floor of the building. It was otherwise empty. So far, the only evidence of those trapped within are two construction helmets fire fighters uncovered in one area. Rescuers are operating under difficult conditions, carefully digging their way through the rubble to try and find the trapped workers.
