President Emmanuel Macron has promised more hospital beds for Covid patients.

France is currently battling a peak of about 5,000 Covid patients in ICUs. On Friday, the country recorded 46,677 new cases and 304 deaths.

As well as the restrictions that came into force on Saturday, from Tuesday people will also need a valid reason to travel more than 10 km (six miles) from their homes.

President Macron had hoped to keep France's coronavirus cases under control without having to impose another lockdown.

However, the country has struggled with an EU-wide delay in the vaccine rollout, as well as several new strains of the virus.
