As night fell, AFP journalists saw rescuers trying to extract a mother and son from the ruins of a collapsed building in Naypyidaw.
Both were seriously injured but rescuers were unable to reach them, a Red Cross worker told AFP.
SKYSCRAPER COLLAPSE
Across the border in Thailand, a 30-storey skyscraper under construction collapsed to a tangled heap of rubble and dust in a matter of seconds.
Officials have said three workers are confirmed dead with dozens more still unaccounted for, many believed trapped in the rubble.
“I heard people calling for help, saying ‘help me’,” Worapat Sukthai, deputy police chief of Bang Sue district, told AFP.
“We estimate that hundreds of people are injured,” he said.
As night fell, around 100 rescue workers assembled at the scene to search for survivors, illuminated by specially erected floodlights.
