Four people were killed and at least 30 others injured when a large section of a Latvian grocery store’s roof – where workers were reportedly planting a winter garden – collapsed, rescue officials said.
One firefighter was among those killed, and seven were injured when another portion of the roof fell on rescue workers as they began searching for survivors in the debris of the Maxima grocery store in the capital, Riga.
Fire and rescue service spokeswoman Viktorija Sembele said more than a dozen fire crews and dog units were searching the wreckage of the building.
It was unclear whether anyone was trapped, but the store is in a densely populated part of the city, not far from the centre.
The authorities said the accident happened at about 6pm local time, during the after-work rush-hour.
Witnesses told Latvian media they heard an explosion, but there were reports that a garden with trees and plants was being built on the store’s sizeable roof. Ms Sembele confirmed that there may have been additional construction.
