An explosion and fire at a factory in western Turkey left 10 workers dead, while rescuers searched for four more believed to be trapped under the debris.

The blast took place at the HABAS steel plant in Aliaga, in the port city of Izmir. The city's governor Suleyman Elban told reporters that 15 people were injured, two of them critically, and that further search and rescue efforts were underway. 

The plant's production line was in the middle of a shift change rather than active production, according to the governor. Only some 200 workers were present instead of the expected 300.

An earlier statement from the governor's office said that the blast happened around noon (09:00 GMT) when an overhead crane toppled into a furnace during the casting of liquid steel. It also said that the authorities were investigating the incident.

Union leader Basaran Aksu said that "the massacre calls for the resignation of the minister of labor."

He warned that "workers' blood" was being shed for profit.
