Half of France under red heatwave alert

France has issued red heatwave alerts for around half the country including Paris for Monday as a heatwave pushes temperatures towards record levels.

On Sunday temperatures in the south-western city of Bordeaux hit 40C (104F).

Earlier, French authorities banned alcohol consumption in public places during the annual Fête de la Musique, a national music festival that draws millions to the streets across the country.

"For all events organised by the state and its agencies, instructions have been given not to offer alcohol," the office of Prime Minister Sébastien Lecornu said.
