A wildfire in northern California has destroyed 10 homes and is threatening 800 more, authorities said, with a number of people forced to evacuate.

The water level has dropped behind the US's tallest dam, reducing the risk of a catastrophic spillway collapse and easing fears that prompted the evacuation of nearly 200,000 people downstream.

DAVID MARTINEZ does not seem to appreciate the enormity of the challenge that lies ahead of him when he takes on Bernard Dunne before his hometown fans at the National Stadium on Saturday night.
