Two women were killed and three workers injured on Tuesday when a crane collapsed at a construction site in the Belgian city of Liege, local authorities said.

"Two people were killed and three injured, two seriously," the mayor of Liege Willy Demeyer was quoted as saying by Belga news agency.

The two women, the manager of a tiling company and her daughter, were in the raised basket of the crane transporting material to the second floor of the building when it collapsed, news agency Belga reported citing the findings of the initial investigation.

The basket fell onto a lorry that contained the three workers, the report said.
