Rescue teams are trying to free a worker buried under rubble in Rome after a medieval tower partially collapsed during renovation work. Italy's national fire department spokesman Luca Cari said they were trying to get the man, who was still stuck hours after the initial collapse, out alive, "but the situation is complex because of the risk of further collapses". The worker had displayed "signs of life" and had been given some protective cover during one of the rescue attempts, Rome's top law enforcement official, prefect Lamberto Giannini, said.
