More than 110,000 police officers, fighter fighters, soldiers and coastguard personnel, as well as some 100 helicopters have been mobilised for Monday's rescue operations, officials added.

"Damage has been made in an extremely wide range of areas, and more than 30,000 people are still being forced to remain in the state of evacuation."
