According to an eyewitness, David Aderibigbe, six of the victims had been rescued.
He said: “Some of the survivors of the incident who have been rescued told us there are no fewer than 23 workers on site and two traders.
“The survivor said one of the traders was trapped with her baby,” Aderibigbe said.
One of the survivors said it was his first day at the site.
