Europe heatwave: Nearly all major Italian cities on red heat alert

Red alerts for extreme heat are in place in most of Italy's main cities as a heatwave intensifies in Europe.
Temperatures are expected to peak on Wednesday, with 23 cities on high alert - from Trieste in the north-east to Messina in the south-west.

The warnings mean the heat poses a threat to everybody, not just vulnerable groups.

Wildfires are also raging across the continent, including in Greece and the Swiss Alps.
