Collapse in Florence, residents: 'We heard a roar and saw a cloud of dust' "I was sitting in my living room, which overlooks the construction site, when at a certain point I heard a noise and saw that an attic had collapsed" "From the window I saw a broken beam where the collapse occurred. I didn't know anyone was left under the rubble," says Miriam, a resident who lives near the site in via Mariti in Florence.

"I didn't imagine such a tragedy and I feel sorry for the victims"
