Vanuatu's Tanna suffering from food shortages

People on the southern Vanuatu island of Tanna are suffering from food shortages after a volcano blanketed a large area in ash.

The National Disaster Management Office said about 28,000 people are affected.

An official, Phillip Meto, said crops and food supplies have been destroyed by the ashfall from Mt Yasur.

The island was already short of food and water after a months-long drought.
