Five construction workers were murdered when a school building under construction in Antwerp, Belgium, fell on Friday, local media reported on Sunday.

According to Belga News Agency, the workers, four Portuguese and one Moldovan, were working on the site when the building partially collapsed.

A total of nine other workers were hurt and sent to the hospital. Eight of them were seriously injured, but their conditions are currently stable.

On Saturday, King Philippe of Belgium and Prime Minister Alexander De Croo paid a visit to the site.

Democo, the construction business in charge of Antwerp's construction projects, committed on Saturday to investigate what happened.

According to figures from the Construction Confederation, approximately 57,000 foreign nationals worked in Belgium's construction sector in 2020, out of a total of more than 300,000 contract and self-employed workers.
