Two World Health Organization experts are heading to the Chinese capital on Friday to lay the groundwork for a larger mission to investigate the origins of the coronavirus.An animal health expert and an epidemiologist will meet Chinese counterparts in Beijing to set the “scope and terms of reference” for a WHO-led international mission aimed at learning how the virus jumped from animals to humans, a WHO statement said.Scientists believe the virus may have originated in bats and was transmitted to another mammal such as a civet cat or an armadillo-like pangolin before being passed on to people.A cluster of infections late last year focused initial attention on a fresh food market in the central Chinese city of Wuhan, but the discovery of earlier cases suggests the animal-to-human jump may have happened elsewhere.In an effort to block future outbreaks, China has cracked down on the trade in wildlife and closed some markets, while enforcing strict containment measures that appear to have virtually stopped new local infections.The WHO mission is politically sensitive, with the U.S. — the top funder of the U.N. body — moving to cut ties with it over allegations it mishandled the outbreak and is biased toward China.“China took the lead in inviting WHO experts to investigate and discuss scientific virus tracing,” Chinese foreign ministry spokesperson Zhao Lijian said Friday.In contrast, he said, the U.S. “not only announced its withdrawal from the World Health Organization, but also politicized the anti-epidemic issue and played a buck-passing game to shift responsibilities.”More than 120 nations called for an investigation into the origins of the virus at the World Health Assembly in May. China has insisted that WHO lead the investigation and for it to wait until the pandemic is brought under control. The U.S., Brazil and India are continuing to see an increasing number of cases.The last WHO coronavirus-specific mission to China was in February, after which the team’s leader, Canadian doctor Bruce Aylward, praised China’s containment efforts and information sharing. Canadian and American officials have since criticized him as being too lenient on China.An Associated Press investigation showed that in January, WHO officials were privately frustrated over the lack of transparency and access in China, according to internal audio recordings. Their complaints included that China delayed releasing the genetic map, or genome, of the virus for more than a week after three different government labs had fully decoded the information.Privately, top WHO leaders complained in meetings in the week of Jan. 6 that China was not sharing enough data to assess how effectively the virus spread between people or what risk it posed to the rest of the world, costing valuable time. 2810

Twitter users across the US reported the social media was out on Thursday evening. The outage was first reported shortly before 6 p.m. ET, but the service began to recover within two hours. It is unclear what caused the outage."We are continuing to monitor the issue, and things appear to have returned to normal. For streams, if your connection was maintained during this period, you should have received available data since this issue also affected the publishing side of Twitter. If you disconnected at all, a Replay will recover any Tweets during your disconnect, and the volume is likely to be very small," Twitter said Thursday evening. According to Down Detector, the outage occurred nationally among thousands of users. 736

US Customs and Border Protection closed road and pedestrian bridges on Sunday at the San Ysidro port of entry, one of the largest land border crossings between San Diego and Tijuana, Mexico.Groups of Central American migrants have been converging on the Mexican border city for days in their quest to gain entry to the United States. Their presence has drawn Mexican troops, protesters and fiery rhetoric from President Donald Trump and Mexican officials.As crowds amassed at San Ysidro, around 500 migrants overwhelmed federal and local Mexican police blockades and rushed toward the border, said freelance reporter Alfredo Alvarez, who is in the crowd.PHOTOS: Migrants converge on Tijuana-San Diego borderThe crowds were made up of men, women and a lot of children, Alvarez said.With bridge and pedestrian border crossings closed in both directions, the migrants headed for the cargo area where the railroad crosses, Alvarez said.They appeared to get close to the border wall, Alvarez said. He could not see from his position if the migrants had managed to get across the actual border.More demonstrations were planned on Sunday at San Ysidro, the busiest land port of entry in the Western Hemisphere, according to the US General Services Administration.The planned demonstrations on both sides of the border prompted CBP to deploy extra personnel to the border crossing, the agency said."The additional personnel, which included CBP officers, US Border Patrol agents, and Air and Marine agents, were recently deployed to the San Diego area from various areas around the country in preparation for the potential arrival of the caravan in Tijuana."The mayor of Tijuana said on Sunday that he would not let the migrants' actions damage the city's relationship with its neighbors across the border. Many residents of Tijuana work, study and visit the United States each day, and the border closures affect them, too, Juan Manuel Gastélum said on Twitter on Sunday.The mayor has said previously that the city cannot support the migrants.  2049
