The fast-moving avalanche “came down with a roar the could be heard at great distance”, local online media site ildolomiti.it said.
The search by helicopter and dogs for any more victims or missing was halted for the night while rescuers evaluated the risk that more of the glacier could break off, Walter Cainelli, president of Trentino Alpine and Speleological Rescue told state television after conducting a rescue mission with a search dog.

Rescuers said blocks of ice were continuing to tumble down. In early evening, a light rain began to fall.
The SUEM dispatch service, which is based in the nearby Veneto region, said 18 people who were above the area where the ice struck would be evacuated by the Alpine rescue corps.
Some of those making the trek in the area where the avalanche barrelled through were tied together by rope, according to local emergency services.
But Milan said some of the hikers might be able to get down by themselves, including by using the peak’s cable car.

SUEM said the avalanche consisted of a “pouring down of snow, ice and rock”. The detached section is known as a serac, or pinnacle of ice.
Dubbed the “queen of the Dolomites”, Marmolada rises about 3300 metres and is the highest of the 18 peaks in that eastern range of the Italian Alps, offering spectacular views of other Alpine peaks.
The rescue service said in a tweet that the segment broke off near Punta Rocca (Rock Point), “along the itinerary normally used to reach the peak”.
It wasn’t immediately clear what caused the section of ice to break away and rush down the peak’s slope. But the intense heat wave gripping Italy since late June loomed as a possible factor.
“The temperatures of these days clearly had influence” on the glacier’s partial collapse, Maurizio Fugatti, the president of Trento province, which borders Marmolada, told Sky TG24 news.
But Milan stressed that high heat, which soared unusually above 10 Celsius on Marmolada’s peak in recent days, was only one possible factor in Sunday’s tragedy.
“There are so many factors that could be involved,” Milan said. Avalanches in general aren’t predictable, he said, and heat’s influence on a glacier “is even more impossible to predict”.
In separate comments to Italian state television, Milan called the recent temperatures “extreme heat” for the peak. “Clearly it’s something abnormal.”
Experts at Italy’s state-run CNR research centre, which has a polar sciences institute, say the glacier won’t exist anymore in the next 25-30 years and much of its volume is already gone.
The Mediterranean basin, shared by southern Europe, the Middle East and northern Africa, has been identified by UN experts as a “climate change hot spot”, likely to suffer heat waves and water shortages, among other consequences.
The injured were flown to several hospitals in the regions of Trentino-Alto Adige and Veneto, according to rescue services.
As in other cases of disasters amid nature in Italy, prosecutors opened an investigation to see if there was any indication of possible wrongdoing linked to the avalanche.
