He asserted that there will be more strictness in enforcing lockdown rules.
"We have to be very careful about hotspots. We will have to keep a close watch on the places which are expected to be converted into hotspots. The creation of new hotspots will further challenge our hard work. The strictness of the fight against corona will further be increased in the next week," he said in his address to the nation.
"There will be a review of every town, police station, every district and every state by April 20 to see how lockdown rules are being followed there and how much that area has protected itself from the infection," he said.
Speaking further, the Prime Minister said: "Till 20th April, all districts, localities, states will be closely monitored, as to how strictly they are implementing norms. States which will not let hotspots increase, they could be allowed to let some important activities resume, but with certain conditions."
The 21-day lockdown, which was announced by the Prime Minister last month, was slated to end today.
Earlier, Odisha, Punjab, Maharashtra, Telangana, Tamil Nadu and Puducherry and have already announced the extension of lockdown.
