Dozens of workers have called for the Italian government to help keep an aluminium factory open on the island of Sardinia.
The loss-making plant, owned by US firm Alcoa, is set to close in November unless a buyer is found.
Hundreds of jobs are threatened in one of Italy’s biggest unemployment blackspots.
Several workers joined a protest outside the factory on Thursday.
Seventy kilometres south of the plant, miners at the Carbosulcis coal mine, have barricaded themselves in.
The mine is also threatened with closure, which would see about 500 jobs lost.
