Rescuers continued to pull bodies from the rubble of a collapsed supermarket in Riga, Latvia, late Friday as the death toll climbed to 48, including three firemen, officials said. Some 35 people were injured and 28 hospitalized after 5,300 square feet of the building's roof caved in, The Associated Press reported. The collapse happened Thursday evening when the building was full of shoppers on their way home from work. It's unclear how many are still trapped inside. Police spokesman Toms Sadovskisk said authorities expected the death toll to climb even higher. Television pictures showed that the Maxima store surrounded by fire trucks and ambulances with rescue workers using mechanical cutters to move debris from the building. Local media said workers had been building a rooftop garden on the store. "It is clear that there has been a problem with fulfillment of construction requirements," said Interior Minister Rihards Kozlovskis said on local television, according to Reuters.
