Philippine police deployed road blocks to enforce a tough new lockdown on about 28 million people in the capital Manila and nearby provinces as the Southeast Asian country reported the region's biggest daily rise in coronavirus cases, Reuters reported.

The area, which accounts for most economic activity in the country and a quarter of the population, has gone back into lockdown for two weeks after restrictions were relaxed in June.

The eased restrictions, in an effort to revive the economy, led to infections soaring more than six-fold to 112,593 and deaths more than doubling to roughly 2,100, piling pressure on a beleaguered healthcare sector.

The health ministry reported 6,352 new cases, marking the biggest daily jump in infections in Southeast Asia and after posting a record rise in five of the past six days.
