A helicopter belonging to Italy's rescue services crashed today in the country's north-eastern Alps, killing all four people on board, DPA quoted officials as saying. The helicopter was flying in bad weather towards the scene of a rockfall, when it struck power lines near the Monte Faloria mountain, a rescue service official, Fabio Calore, told television news channel Sky TG24. The bodies of the dead (a pilot, two technicians and a doctor) were taken to a hospital in the nearby town of Cortina D'Ampezzo, news reports said.
