Nigeria will start easing a coronavirus lockdown covering its largest city Lagos and capital Abuja from May 4, President Muhammadu Buhari said on Monday. “I have approved a phased and gradual easing of lockdown measures,” Buhari said in a televised broadcast. More than 25 million residents in Abuja, Lagos and neighbouring Ogun state have been under federal lockdown since March 30 and other states have introduced their own restrictions.
