Nigerian President Muhammadu Buhari has extended the country's lockdown by another 14 days in a live, televised address to the nation. 

The ongoing movement restrictions apply largely to Lagos and Ogun. Buhari says the measures are necessary to contain the spread of the novel coronavirus.

Initial 14-day lockdowns in the three states began on March 30. Buhari said it was crucial to extend the lockdown due to an “alarming” increase in positive cases in a number of states .

"It is a matter of life and death,”Buhari said of the nation's response.
