Italian rescue teams on Wednesday found two more victims of the glacier collapse in the Alps that is feared to have killed up to 12 people and is being blamed on rising temperatures.

At least nine people are now confirmed to have been killed in the avalanche on Sunday on the Marmolada.

Officials have attributed the tragedy to scorching temperatures; when the glacier collapsed, the temperature at the mountain peak was reportedly around 10 degrees Celsius, when a normal temperature for this time of year is below zero.

Rescue coordinators hope to supplement the work of drones and helicopters by sending a team of experts and search dogs to the lower part of the site on Thursday, when the weather is forecast to be clearer.

Parts of the mountain will remain shut off to tourists to allow rescue teams to operate and prevent climbers from accessing potentially dangerous areas.
