Pope Francis' personal doctor has died of complications related to COVID-19, the Vatican's newspaper L’Osservatore Romano announced Saturday.

Fabrizio Soccorsi, 78, was being treated for cancer at a hospital in Rome at the time of his death, according to the newspaper.

Soccorsi was chosen by the pontiff to be his personal physician in 2015.

In an interview with Italian television channel Canale 5 that aired Sunday night, Francis said COVID-19 vaccinations will begin at the Vatican next week and that he will get the shot.

Sputnik V, a COVID-19 vaccine developed by Russia, has been registered by the Palestinian Ministry of Health for emergency use in Palestinian self-ruled territory, Russia's sovereign wealth fund announced Monday.

The first shipment of doses is expected to arrive next month, according to a press release from the Russian Direct Investment Fund (RDIF), which is responsible for worldwide marketing of the vaccine.

The RDIF didn't say how many doses would be shipped to the Palestinian Authority -- which governs parts of the West Bank under interim peace deals with Israel -- but that supplies would be facilitated by manufacturing partners in India, China, South Korea and other countries.

As of Jan. 5, the World Health Organization had recorded more than 157,000 confirmed cases of COVID-19 in the occupied Palestinian territories, including at least 1,578 deaths.

More than 50,000 doses of a COVID-19 vaccine developed by U.S. biotechnology company Moderna are expected to arrive in France on Monday, according to a statement from the country's health ministry.

France should have nearly 8 million doses of the Moderna vaccine by the end of June, the health ministry said.

Last week, the European Medicines Agency authorized the Moderna vaccine for use across the European Union. Another COVID-19 vaccine developed by U.S. pharmaceutical giant Pfizer and its German partner BioNTech was approved two weeks earlier. Both vaccines are administered in two doses.

French Health Minister Olivier Veran told Europe 1 radio that the Moderna doses will then be sent to towns and cities with the highest virus circulation. The doses should reach vaccination centers by Wednesday, he said.

By the end of the weekend, Veran said, more than 100,000 people should have received a first dose of the vaccine.

France has faced criticism for a slow vaccine rollout compared to its EU neighbours.

A new, more infectious variant of the novel coronavirus that was first detected in the United Kingdom has now been discovered in Mexico.

The strain, called B117, was confirmed in a 56-year-old foreign citizen who had traveled from Amsterdam to Mexico City on Dec. 28, and then to the northeastern city of Matamoros the following day. The individual was asymptomatic when he arrived in the country, according to Mexico's director general of epidemiology, Jose Luis Alomia Zegarra.

After testing positive for COVID-19, the man was admitted to a Mexican hospital last week where he remains intubated, Zegarra said.

Genomic sequencing of the patient's sample that tested positive for COVID-19 revealed its B117 lineage. More than 500 suspected cases of the U.K. variant have been tested in Mexico, but this is the country's first verified case, according to Zegarra.

Mexican health authorities are tracking contacts of the patient, including people who traveled on the same flight. Two individuals who showed symptoms have since tested negative for COVID-19, while another 31 are asymptomatic and remain in isolation. Officials have been unable to locate 12 others, Zegarra said.

The highly contagious strain has become prevalent in London and other parts of southeast England, after first being identified in the English county of Kent in September. The B117 variant has since been detected in over a dozen other countries.

Japanese Prime Minister Yoshihide Suga declared a state of emergency in seven additional areas on Wednesday, as COVID-19 cases continued to climb.

The latest state of emergency was declared for the prefectures of Osaka, Hyogo, Kyoto, Aichi, Gifu, Fukuoka, and Tochigi.

The move comes one week after Suga declared a state of emergency in Tokyo and three neighboring prefectures due to rising infections and a growing death toll.

A state of emergency declaration gives the governors of those respective regions the authority to ask residents for cooperation in efforts to curb the spread of the virus. There are currently no legal ramifications for non-compliance.

Under the state of emergency, which takes immediate effect and is expected to end Feb. 7 for all 11 prefectures, Suga said governors will ask residents to refrain from dining out and to stay home after 8 p.m. unless for essential reasons. They will also ask companies to decrease the number of employees commuting to work by 70%.

Suga said bars and restaurants will be asked to stop serving alcohol by 7 p.m. and to close by 8 p.m. Governors may disclose the name of the businesses that don't comply, while those that do will be given 1.8 million Japanese yen ($17,000) per month.

Spectator events will be limited to an audience of 5,000 people. Schools will not be asked to close, according to Suga.

Suga's predecessor, Shinzo Abe, declared a nationwide state of emergency relatively early in the pandemic in April, which lasted for a month. At that time, residents were asked to reduce person-to-person contact by 80% and to practice "jishuku," or "self-restraint," by staying at home and closing non-essential businesses.

The Japanese Ministry of Health, Labor and Welfare registered 4,521 newly confirmed cases of COVID-19 as well as 51 additional deaths from the disease on Tuesday, bringing the country's cumulative total to 295,257 cases with at least 4,144 deaths.
