A large chunk of Alpine glacier broke loose Sunday afternoon and slid down a mountainside, slamming into more than a dozen hikers on a popular trail on the peak. At least four people were killed, Italy's state television said, and seven others were injured.
RAI state television didn't cite a source for its report of fatalities. But earlier the National Alpine and Cave Rescue Corps tweeted that the search of the involved area of Marmolada peak involved at least five helicopters and rescue dogs. Separately, emergency dispatchers in northeast Italy tweeted that about 15 hikers were believed to have been in the stricken area.
