"It's gonna be a rough few weeks," the official said.

One person jumped from the second floor of the building to avoid being caught in the collapse, the official said. Those who were trapped were able to communicate with rescuers via tapping.

The official described the incident as a lean-to/pancake collapse, allowing for "a lot of void spaces."
