A medieval tower in central Rome has partly collapsed twice during renovations, injuring one worker and trapping another.

Falling debris from the initial collapse of the Torre dei Conti, just after 11.30am (0930 GMT), close to the Roman Forum ruins, hit a 64-year-old worker, the Ansa news agency reported. He was taken to San Giovanni hospital in a critical condition although Francesco Rocca, Lazio’s regional president, said his injuries were not life threatening.

With hundreds of tourists and passersby looking on, firefighters rescued three other workers from scaffolding on the 29-metre high tower. During the operation, at about 1pm, an internal section of the tower collapsed, leaving one worker trapped on an upper floor.
