At least 10 were injured and an unknown number of workers remain trapped inside the under-construction structure.
At least two workers were killed and more than 10 injured when a building under construction inside the Burapa University campus in Chon Buri collapsed Sunday night. A still unknown number of workers were believed to still be trapped under the debris.
Reports of a third worker killed could still not be confirmed.
The building, part of a cluster of buildings in the campus, collapsed while fresh cement was being poured for the second or third floor, initial reports said.
As of 1.07am rescue workers were still trying to help those still trapped at the collapsed Burapha Uni site.
