Mexico’s health ministry on Monday reported 4,973 new coronavirus cases and 342 additional deaths, bringing the country’s total cases to 395,489 and death toll to 44,022. The figures were published earlier in the day by Johns Hopkins University. Mexico has the fourth highest coronavirus death tally worldwide. The government has said the real number of infected people is likely significantly higher than the confirmed cases. Anti-racism protesters plan to demonstrate in downtown Sydney on Tuesday despite court rulings that the gathering is illegal due to the pandemic threat, AP reports. Organiser Paddy Gibson said the gathering would be safer than going to a crowded shopping mall or many Sydney workplaces. “We all must be Covid-safe but we need to stand together to ... say that Black lives matter in Australia,” Gibson told Nine Network television. Gibson had organised the demonstration with the family of David Dungay, a 26-year-old Indigenous man who died in 2015 while being restrained in a Sydney prison after repeatedly saying: “I can’t breathe.” The demonstrators have gathered more than 100,000 signatures on a petition calling for his prison guards to be charged. A New South Wales state Supreme Court judge on Sunday accepted a police submission that the possibility of community transmission of Covid-19 made the demonstration too risky to proceed. An appeals court on Monday dismissed the protesters’ challenge which contended the judge did not have the authority to prohibit the rally. The court rulings increase the legal powers available to police to use against protesters. Outdoor gatherings are limited to 20 people in New South Wales due to the pandemic threat. Here is more on the planned protest: Youth climate activists are to advise the UN secretary general on the climate emergency as part of a new effort to bring young people into decision-making and planning on the crisis. Seven young people, aged between 18 and 28, will take on roles to “provide perspectives, ideas and solutions” to the secretary general, António Guterres, aimed at helping to scale up global climate action in the recovery from the coronavirus crisis and ahead of a crunch summit next year on the climate. Guterres said: “We need urgent action now, to recover better from Covid-19, to confront injustice and inequality, and address climate disruption. We have seen young people on the front lines of climate action, showing us what bold leadership looks like.” The new advisory group includes: a young woman from Sudan, Nisreen Elsaim, who is already a junior negotiator at intergovernmental climate forums; an economist, Vladislav Kaim from Moldova; Paloma Costa, a lawyer and human rights defender from Brazil; and from India, Archana Soreng, who works on the traditional knowledge and cultural practices of indigenous people: WHO says Covid-19 is "easily the most severe" crisis it has faced Thursday this week will mark six months since the World Health Organization declared the Covid-19 pandemic “public health emergency of international concern”. WHO chief Tedros Adhanom Ghebreyesus told reporters on Monday night, “This is the sixth time a global health emergency has been declared under the International Health Regulations, but it is easily the most severe,” saying that cases have roughly doubled in the last six weeks, as the pandemic “continues to accelerate.” “When I declared a public health emergency of international concern on the 30th of January – the highest level of alarm under international law – there were less than 100 cases outside of China, and no deaths,” he added.
