WASHINGTON: Two new studies provide more evidence that the coronavirus pandemic originated in a Wuhan, China market where live animals were sold – further bolstering the theory that the virus emerged in the wild rather than escaping from a Chinese lab.
The research, published online Tuesday by the journal Science, shows that the Huanan Seafood Wholesale Market was likely the early epicenter of the scourge that has now killed nearly 6.4 million people around the world. Scientists conclude that the virus that causes COVID-19, SARS-CoV-2, likely spilled from animals into people two separate times.
“All this evidence tells us the same thing: It points right to this particular market in the middle of Wuhan,” said Kristian Andersen a professor in the Department of Immunology and Microbiology at Scripps Research and coauthor of one of the studies. “I was quite convinced of the lab leak myself until we dove into this very carefully and looked at it much closer.”
In one study, which incorporated data collected by Chinese scientists, University of Arizona evolutionary biologist Michael Worobey and his colleagues used mapping tools to estimate the locations of more than 150 of the earliest reported COVID-19 cases from December 2019. They also mapped cases from January and February 2020 using data from a social media app that had created a channel for people with COVID-19 to get help.
They asked, “Of all the locations that the early cases could have lived, where did they live? And it turned out when we were able to look at this, there was this extraordinary pattern where the highest density of cases was both extremely near to and very centered on this market,” Worobey said at a press briefing. “Crucially, this applies both to all cases in December and also to cases with no known link to the market … And this is an indication that the virus started spreading in people who worked at the market but then started to spread into the local community.”
Andersen said they found case clusters inside the market, too, “and that clustering is very, very specifically in the parts of the market” where they now know people were selling wildlife, such as raccoon dogs, that are susceptible to infection with the coronavirus.
In the other study, scientists analyzed the genomic diversity of the virus inside and outside of China starting with the earliest sample genomes in December 2019 and extending through mid-February 2020. They found that two lineages – A and B – marked the pandemic’s beginning in Wuhan. Study coauthor Joel Wertheim, a viral evolution expert at the University of California, San Diego, pointed out that lineage A is more genetically similar to bat coronaviruses, but lineage B appears to have begun spreading earlier in humans, particularly at the market.
“Now I realize it sounds like I just said that a once-in-a-generation event happened twice in short succession,” Wertheim said. But certain conditions were in place — such as people and animals in close proximity and a virus that can spread from animals to people and from person to person. So “barriers to spillover have been lowered such that multiple introductions, we believe, should actually be expected,” he said.
Many scientists believe the virus jumped from bats to humans, either directly or through another animal. But in June, the World Health Organization recommended a deeper probe into whether a lab accident may be to blame. Critics had said the WHO was too quick to dismiss the lab leak theory.
“Have we disproven the lab leak theory? No, we have not,” Andersen said. “But I think what’s really important here is there are possible scenarios and there are plausible scenarios and it’s really important to understand that possible does not mean equally likely.”
The pandemic’s origins remain controversial. Some scientists believe a lab leak is more likely and others remain open to both possibilities. But Matthew Aliota, a researcher in the college of veterinary medicine at the University of Minnesota, said in his mind the pair of studies “kind of puts to rest, hopefully, the lab leak hypothesis.”
“Both of these two studies really provide compelling evidence for the natural origin hypothesis,” said Aliota, who wasn’t involved in either study. Since sampling an animal that was at the market is impossible, “this is maybe as close to a smoking gun as you could get.”

Saudi Ambassador to Japan highlights the country’s attractions ahead of Osaka Expo
- The tour — held in various parts of Japan — aims to show how Saudi Arabia is not just a distant place, but a relevant and engaging destination for all
TOKYO: Saudi Arabia’s Ambassador to Japan Dr. Ghazi Faisal Binzagr attended the Tokyo stop of the “Meet Saudi Arabia Tour” to promote the Kingdom’s pavilion at the Osaka Kansai Expo, which opens on April 13.
The tour — held in various parts of Japan — aims to show how Saudi Arabia is not just a distant place, but a relevant and engaging destination for all.
Ambassador Binzagr, emphasizing the unique aspects of Saudi Arabia’s “rich culture and a fascinating history,” believes these elements have a special appeal to the people of Japan.
“We have beautiful, exciting things to showcase, but this is just a small glimpse of what we have to show about the past, the present and the future of Saudi Arabia,” Ambassador Binzagr told Arab News Japan.
“There are lots of things that you can touch and feel about our culture, from our heritage, from the emotion of our cities today and our life in the midst of a very exciting transformation that we are undergoing in Saudi Arabia.”
The Tour offers visitors a chance to experience various aspects of Saudi culture, including Saudi Arabian coffee and date pairing, a cooking demonstration of traditional sweets, and traditional Saudi music and costumes.
“We’re counting down to the last days before our opening in Osaka,” Ambassador Binzagr said about the Expo. “We’re almost completed and ready. I had the privilege of touring the site two days ago, and the final touches are being made now. With glimpses of the future we’re heading towards, I am very excited to welcome everyone to Osaka.”
One of the main themes of the Saudi Arabian pavilion is the building itself. The pavilion has been described as a “masterpiece” and is said to embody the flow of Saudi Vision 2030 and the transformation from past to future, sensitivity to the environment, and design elements that blend heritage with technology and vision.
“Looking at it, I see the transformation of Saudi Arabia and what’s happening in our vibrant country,” Dr. Binzagr said. “But our focus is not just on the present, but also on the promising future of Saudi Arabia. We want to inspire people with the potential and relevance of our future. We want people to see a sample of it so that they think not just about joining us in Osaka, but beyond that to visiting our country.”
Thematically, it projects an invitation to the world to step inside Saudi Arabia and to experience it. The building itself aims to reflect harmony – melding the desert environment with architectural aspects that both shield people from nature’s elements and celebrates those elements at the same time.
US Secret Service shoots armed man near White House: spokesman
- Man had been hospitalized and his condition was “unknown”
- Statement did not specify whether the White House or Trump may have been his intended target
WASHINGTON: US Secret Service agents shot an armed man near the White House during the night, an agency spokesman said early Sunday, while President Donald Trump was spending the weekend at his Mar-a-Lago residence in Florida.
The man had been hospitalized and his condition was “unknown,” the spokesman said in a statement that did not specify whether the White House or Trump may have been the intended target.
No injuries to Secret Service agents were reported, according to the statement posted by spokesman Anthony Guglielmi on social media platform X.
The agents had been warned by local police of a “suicidal” man traveling to Washington from Indiana and around midnight found his parked vehicle near 17th and F Streets, the statement said — very near the White House.
They then spotted an individual nearby who matched the description they had been given, the statement said.
“As officers approached, the individual brandished a firearm and an armed confrontation ensued, during which shots were fired by our personnel,” the statement said.
“The suspect was transported to an area hospital and his condition is unknown,” it said, adding that Washington police were investigating.
Bangladeshi businesses seek closer ties with UAE on skills development, trade
- Dhaka Chamber of Commerce and Industry recently signed MoUs with Dubai, Sharjah chambers
- Bangladeshi private sectors see UAE as ‘major gateway’ to Middle East, North Africa
Dhaka: Bangladeshi businesses are seeking closer ties with the UAE on skills development, trade and investments, the Dhaka Chamber of Commerce and Industry said on Sunday after it signed agreements with its Emirati counterparts to strengthen economic cooperation.
The UAE is Bangladesh’s largest trading partner in the Middle East, with their bilateral trade volume valued at around $2 billion in 2024.
The Gulf state — home to about 1.2 million Bangladeshi expats — is also Bangladesh’s fifth-largest foreign investor.
DCCI President Taskeen Ahmed led a 29-member business delegation to the UAE last month, where he signed preliminary agreements with the Dubai Chambers and the Sharjah Chamber of Commerce and Industry to boost trade and investments between their two countries.
Bangladeshi businesses are eyeing cooperation in a number of key areas, including trade and market access, energy and financial sectors, tourism and hospitality, infrastructure and logistics, Ahmed said.
“Closer trade relations between Bangladesh and the UAE present a significant opportunity to strengthen our economic landscape across multiple sectors. I firmly believe that enhanced trade ties with the UAE can be a game-changer for Bangladesh,” he told Arab News.
“The UAE serves as a major gateway to the Middle East, North Africa, and beyond. Expanding our trade partnership will create greater market access for Bangladeshi products.”
The Dhaka Chamber is also seeking stronger collaboration in technology and skills development.
“The UAE is highly advanced in digital infrastructure, logistics, and financial services. Stronger collaboration can facilitate knowledge transfer and capacity-building, helping Bangladeshi industries adopt global best practices, enhance productivity, and become more competitive,” Ahmed added.
Under the newly signed memoranda of understanding, DCCI is set to collaborate with its Emirati counterparts “to promote bilateral trade, investment matchmaking and joint economic discussions,” with activities focused on exchanging trade delegations and strengthening business networking platforms.
“To further boost collaboration, Bangladesh aims to activate the Bangladesh-UAE Business Council, focusing on trade finance, private equity, and expanding Islamic finance,” Ahmed said.
Business leaders from the two countries are also involved in discussions to set up training centers “to improve the skill set of Bangladeshi workers” who are seeking employment in the UAE, while a direct shipping route between Chattogram and Dubai is being discussed to enhance trade efficiency.
“I believe that this mutual cooperation will enhance the value of our national bilateral relations … These initiatives will further deepen the economic and trade relationship between Bangladesh and the UAE following the MoU signing.”
Russia says captures another east Ukraine village
MOSCOW: Russia announced Sunday the capture of another eastern Ukrainian village, in the Donetsk region, as its forces advanced toward the central Dnipropetrovsk region.
The defence ministry said in a briefing that its troops had captured the village of Kostyantynopil, about 50 kilometres (30 miles) west of the Russia-controlled city of Donetsk.
Russian troops have been advancing steadily in the Donetsk region and are now close to Dnipropetrovsk, which so far has been free of fighting. Kostyantynopil is around 13 kilometres (eight miles) from the regional border line.
The village was founded in the 18th century by Greek settlers from Crimea, who named it after the ancient city of Constantinople.
Police say Pakistan Taliban attack kills four paramilitary troops
- At least four Pakistani paramilitary troops were killed when local Taliban fighters attacked a security checkpoint in a northwestern border region, a police official said on Sunday
PESHAWAR: At least four Pakistani paramilitary troops were killed when local Taliban fighters attacked a security checkpoint in a northwestern border region, a police official said on Sunday.
The attack occurred in Kurram district, located on the border with Afghanistan, in Khyber Pakhtunkhwa province, where there has been a rise in violence in recent years.
“Heavily armed militants” launched the attack on Sunday morning, a police official told AFP on condition of anonymity because he was not authorized to speak to the media.
“At least four security personnel were martyred, and seven others were injured,” he said.
Violence has increased in Pakistan since the Afghan Taliban returned to power in Kabul in August 2021.
The Pakistani Taliban — known as Tehreek-e-Taliban Pakistan (TTP) — is the most active militant group in the northwestern region and regularly targets security forces.
Islamabad accuses Kabul’s rulers of failing to root out militants sheltering on Afghan soil as they prepare to stage assaults on Pakistan, a charge the Taliban government denies.
Last week, 13 civilians and five soldiers were killed when suicide bombers drove two car bombs into an army compound in the Bannu district of the same province.
Last year was the deadliest in a decade for Pakistan, home to 250 million people, with a surge in attacks that killed more than 1,600 people, according to the Center for Research and Security Studies, an Islamabad-based analysis group.
