Japan's government is preparing social restrictions in Tokyo and other regions as the omicron variant of the coronavirus infects more people.

Japan has never had a lockdown during the pandemic but has focused instead on asking restaurants and bars to close early. Crowds are back in many parts of Japan, with people packing stores and events, while COVID-19 cases jump.

Japanese Prime Minister Fumio Kishida told parliament on Monday that fighting the pandemic and strengthening defense are his government's top priorities.

Kishida delivered a speech opening this year's parliamentary session hours after North Korea test-fired two possible ballistic missiles — its fourth tests this month.

Greece imposed a vaccination mandate Monday for people 60 and older, as the country's vaccination rate remains below the European Union average and a spike in infections has put sustained pressure on Greek hospitals.

Older people failing to get vaccinated will face penalties, starting at a 50-euro ($57) fine in January and followed by a monthly fine of 100 euros ($114) after that.

China has restored railway freight traffic with North Korea that had been suspended over pandemic concerns, its foreign ministry said Monday.

Ministry spokesperson Zhao Lijian said the connection across the Yalu River between China's Dandong and Sinuiju in North Korea had been restored after "friendly consultation between the two sides."

Chinese President Xi Jinping called Monday for greater world cooperation against COVID-19 and pledged to send an additional 1 billion doses of vaccine to other countries, while urging other powers to discard a "Cold-War mentality" at a time of rising geopolitical tensions — a veiled swipe at the United States.

The Chinese leader touted his country's efforts to share vaccines, fight climate change and promote development at home and abroad as he delivered the opening speech of a virtual gathering hosted by the World Economic Forum. The online event is being held in place of its annual January meeting in Davos, Switzerland, because of health concerns linked to the coronavirus pandemic.

A World Health Organization official warned last week of a "closing window of opportunity" for European countries to prevent their health care systems from being overwhelmed as the omicron variant produces near-vertical growth in coronavirus infections.

In France, Britain and Spain, nations with comparatively strong national health programs, that window may already be closed.

Novak Djokovic lost his final bid to avoid deportation from Australia on Sunday, ending a sensational 11-day battle over his Covid-19 vaccination status and dashing his dream of a record 21st Grand Slam.

Tens of thousands of devout Hindus, led by heads of monasteries and ash-smeared ascetics, took a holy dip into the frigid waters of the Ganges River in northern India on Friday despite rising COVID-19 infections in the country.

Hindu pilgrims congregated at the Sangam, the confluence of three rivers — the Ganges, the Yamuna and the mythical Saraswati — in Prayagraj city, 200 km (124 miles) northeast of Lucknow, the state capital of Uttar Pradesh, to participate in the Magh Mela festival, one of the most sacred pilgrimages in Hinduism. They bathed in the Ganges waters, a ritual Hindus believe will wash away their sins and free them from the cycle of death and rebirth.

Bayern Munich left back Alphonso Davies has been sidelined with evidence of heart muscle inflammation after being infected with the coronavirus, coach Julian Nagelsmann said Friday.

The Canada international will be out of action for at least "the coming weeks" after the inflammation, known as myocarditis, was detected in a follow-up examination after his return to training this week, Nagelsmann said. The coach described the inflammation as "mild" and "not so dramatic," citing the results of an ultrasound examination.

Shops, bars and restaurants in a southern Dutch town opened Friday in a protest action that underscored growing anger at weeks of coronavirus lockdown measures, a day before some of the restrictions are expected to be eased.

A local broadcaster showed people eating and drinking at outdoor tables of restaurants in the main street of Valkenburg in open defiance of a lockdown in the Netherlands. Authorities in the tourist town, which was devastated by flooding last year, didn't take action to enforce coronavirus restrictions.
