As countries including Germany, Norway and Australia start to ease coronavirus restrictions, the World Health Organization has cautioned against a hasty lifting of protective measures, warning “the worst is yet ahead of us.”

Tedros Adhanom Ghebreyesus: “We want to reemphasize that easing restrictions is not the end of epidemic in any country. Ending the epidemic will require a sustained effort on the part of individuals, communities and governments to continue suppressing and controlling this deadly virus.”

In Britain, a government official has said the nationwide lockdown could last for three more months as the official death toll tops 16,000. New data suggests the COVID-19 death toll in parts of the U.K. is up to 40% higher than the hospitals-only figures reported by the government earlier this month.

On Monday, France became the fourth country to report over 20,000 deaths.

In the Philippines, authoritarian President Rodrigo Duterte has threatened to impose martial law to enforce lockdown and social distancing measures. Duterte previously said police and military should shoot people dead if they flouted lockdown measures. Police say 120,000 people have been arrested or given warnings for violating government-imposed rules.
