"I saw one guy was working and then 'boom' and I saw the whole building collapsed... I'm also traumatised. It is very sad," Theresa Jeyi, a local councilor, told reporters at the scene.

According to the provincial administration, police and rescue teams with sniffer dogs were on the scene.

Rescue professionals on site were attempting to recollect where they heard people's pleas, according to George Mayor Leon van Wyk, while rescue equipment was on its way.
