A third section of the roof at a Latvian supermarket where 54 people were killed has collapsed but rescue workers say no one was injured.
Fire and Rescue Service spokeswoman Viktorija Sembele says the roof collapsed in an area where firefighters were not working, but the service immediately recalled its people from inside to ensure there were no casualties.
The service later tweeted that no one was injured.
The service says the entire construction is unstable and the remaining debris to be cleared is particularly dangerous. Video taken at the scene showed a huge portion of the roof falling in while rescuers worked nearby.
