A citizen of Armenia Naira Grigoryan was among those killed in the Latvian supermarket collapse, Foreign Ministry press service reported.

The death toll from the collapse of a roof at a supermarket in Latvia's capital has climbed to 45, making it the Baltic state's deadliest accident since it won independence from the Soviet Union in 1991, local media reported.

Latvia's State Fire and Rescue Service confirmed the revised toll, CNN said citing Latvian media.

Rescue Service spokeswoman Viktorija Sembele earlier said 35 people had also been injured in Thursday November 21 collapse at the Maxima supermarket, in western Riga.

Search teams continue to comb the rubble for more bodies, with the number of dead expected to rise, Sembele said.
