Elsewhere in the world, Brazil registered a new record number of daily cases of more than 137,000 on Tuesday.

President Jair Bolsonaro, an avowed vaccine sceptic who has downplayed Omicron, is increasingly under fire for his handling of the pandemic, and he is on course to lose the country's October presidential election, according to polls.
略 In Asia, Japan was set to tighten restrictions across the country, including Tokyo, as it battles record infections fuelled by Omicron while China partially relaxed transport restrictions in the megacity of Xi'an where millions have been confined to their homes for weeks.
略 Japanese experts on Wednesday backed placing 13 regions "under quasi-emergency measures from January 21 to February 13" Daishiro Yamagiwa, minister in charge of coronavirus affairs, told reporters.
略 China's resumption of some inter-city train routes in Xi'an from Tuesday comes just before the Lunar New Year holiday later this month, traditionally a period of mass travel.
略 It also comes as Beijing battles multiple clusters that are testing its enforcement of a strict "zero-Covid" approach ahead of next month's Winter Olympics.
