Tonga tsunami: Anxious wait for news after Tonga cut off

Tongans living overseas are facing an anxious wait for news of loved ones after a volcano triggered a tsunami.

The underwater volcano erupted on Saturday, about 65km (40 miles) north of the capital Nuku’alofa.

The eruption, which was heard as far away as the US, caused waves higher than a metre to crash into Tonga.

Local authorities have not confirmed any deaths but communications are crippled, making it difficult to establish the scale of the destruction.
