A medieval tower undergoing renovation in central Rome partially collapsed Monday, leaving one worker trapped under rubble, authorities said.
Part of the Torre dei Conti collapsed just after 11:30 am (1030 GMT), sending rubble into the street and a thick white cloud of dust into the air.
"It's a very complex situation for the firefighters because there is a person trapped inside," Rome Prefect Lamberto Giannini told reporters.
The trapped worker, a Romanian national, was "conscious", the Romanian foreign ministry said.
Three other workers were evacuated from the site, one of them in a critical condition, a spokesman for the fire service told AFP.
