The tiny South Pacific archipelago of Vanuatu is reeling from a category five cyclone that left at least eight dead and dozens wounded. Vanuatu President Baldwin Lonsdale called Cyclone Pam a "monster" that destroyed as much as 90 percent of the capital city Port Vila's buildings and infrastructure, while its damage to outlying remote islands remains unclear. Speaking in Japan, where he had been attending a conference, Lonsdale said even he could not reach his family because of power outages. Authorities had still not heard from outlying islands and were trying to determine the scale of destruction. Aid workers have started to deploy to Port Vila while Lonsdale was expected to return Monday. UNICEF estimates 54,000 children are among those affected by the storm.
