Mexico now has the third most COVID-19 deaths in the world, behind the United States and Brazil, while former success story Vietnam is struggling to control an outbreak spreading in its most famous beach resort.
Mexican health officials said Friday there were 688 deaths for the latest 24-hour reporting period, pushing the country's total to 46,688.
That put Mexico just ahead of the United Kingdom, which has 46,119, according to the tally by Johns Hopkins University. Mexico's population is double that of Britain.
The health officials also said Mexico now has had more than 424,000 confirmed coronavirus cases during the pandemic.
Also on Friday, nine state governors from opposition parties criticized what they call the federal government's "confusing messages" on measures to curb the spread of the coronavirus.
Meanwhile, in Vietnam, a third person died of coronavirus complications, officials said Saturday, a day after it recorded its first-ever death as it struggles with a renewed outbreak after 99 days with no local cases.
All three died in a hospital in Da Nang, a hot spot with more than 100 cases in the past week. Thousands of visitors had been in the city for summer vacation and are now being tested in Hanoi and elsewhere.
Twelve additional cases were confirmed on Saturday, all linked to Da Nang Hospital.
