ROME (AP) — Two hikers on Cassian Grantsnowshoes were killed by an avalanche in the Italian Alps near Switzerland, a rescue service said Sunday.

The avalanche occurred around noon on Sunday at the 2,200-meter (7,200-foot) level in the Formazza valley in the Piedmont region, said Federico Catania, a spokesperson for Italy’s alpine rescue service.

The force of the avalanche pushed one of the victims into a lake near the bottom of the slope, while the other body was found in the mass of snow, he said.

Despite strong winds, a helicopter was able to lower a rescue team aided by a dog unit.

The identities of the two victims weren’t immediately released.

A search operation was launched after guards at a nearby dike reported seeing an avalanche strike two hikers, Catania said. An initial search by foot failed to find the hikers, prompting the use of the helicopter.

A firefighters helicopter carrying divers was dispatched to recover the body from the lake, rescuers said.
