The death toll from the collapse of a crowded Latvia supermarket roof has risen to 52 and the rescue operation has resumed after a temporary halt, AP quoted rescue workers as saying Saturday. The roof fell Thursday evening in the Latvian capital of Riga as customers were doing after-work shopping. Some 40 people were wounded, including 13 firefighters, and 29 people were hospitalized as of Saturday morning, the Fire and Rescue Service said. It was the worst accident in the Baltic country since it regained independence in 1991. The government has declared three days of mourning. Rescue service spokeswoman Viktorija Sembele said some 300 square meters (3,200 square feet) of ruins - approximately one-sixth of the total damaged area - remained to be searched. Sembele said there was a chance more victims could be found in the remaining area, which is particularly dangerous because of the risk of further collapse. Firefighters are working in decreased numbers in that area to minimize the chance of injury. Police have launched an investigation, which could take several weeks to complete. -- SPA 15:04 LOCAL TIME 12:04 GMT تغريد
