10 people, including a family of nine, have died in floods around Palermo on the southern Italian island of Sicily, rescue services said on Sunday.
The radio report said one man survived the house flood late Saturday night by clinging to a tree. The survivor used his cellphone to call for help.
State TV also said two people were killed by the storm in the outskirts of Agrigento, a Sicilian tourist town famed for its ancient Greek temples.
Storms had battered northern Italy earlier in the week, killing at least 15 people, uprooting millions of trees near Alpine valleys and leaving several Italian villages without electricity or road access for days.
