Rescuers have made contact with at least 10 survivors Friday who huddled for two days in the rubble of a resort hotel buried under tons of snow that roared down a mountainside in central Italy, an official said.

Several of those trapped were brought to safety through tunnels carved through the snow while others awaited rescuers. The spokesman for Italy’s firefighting service, Luca Cari, told reporters that a total of 10 people have been detected so far in the rubble of the hotel even as the death toll climbed to four.

La Repubblica and Corriere della Sera report that rescuers found survivors at the Rigopiano Hotel. Two of them, a woman her little boy Gianfilippo, were pulled from the rubble after 43 hours after the avalanche. Adriana’s daughter, Ludovica, also seems to be among the survivors.
