Dozens reported killed in Vanuatu cyclone

Vanuatu's President Baldwin Lonsdale has called for international help after Cyclone Pam ripped through the Pacific archipelago.

Describing it as a "calamity", he said he spoke with a "heavy heart".

Aid agencies say the cyclone, which veered off its expected course on Saturday and struck populated areas, has caused "complete devastation".
