Philippine President Rodrigo Duterte has ordered the arrest of unvaccinated people who violate stay-at-home orders aimed at curbing “galloping” coronavirus infections driven by the Omicron variant, AFP reports.

The government tightened restrictions in Manila and several provinces and cities this week. Unvaccinated people among the capital's 13 million people were ordered to stay home, after infection numbers tripled in the last two days.

Health officials said infections were projected to increase further in the coming days and would peak by the end of the month.

“Because it's a national emergency, it is my position that we can restrain” people who have not got their shots, Duterte said in a pre-recorded message.
