At least two people have died and at least 25 are missing after a powerful storm hit southern France and north-western Italy.

Named Alex, it brought fierce winds and torrential rains causing severe floods.

A number of villages suffered serious damage around the southern city of Nice. Its mayor described it as the worst flooding in living memory.

In northern Italy, roads and bridges were swept away by floodwater, while several rivers overflowed their banks.

The once "temperate" climate of Western Europe is becoming increasingly brutal.
