The UK has accused Syria and Russia of preventing independent chemical weapons experts from entering the city of Douma, hit by a suspected gas attack that Western leaders have blamed on the Syrian government.A fact-finding team from the Organization for the Prohibition of Chemical Weapons (OPCW) arrived in Syria on Saturday, the same day the US, UK and France carried out airstrikes against Syrian government targets in response to the April 7 attack in Douma.But by Monday, the team had still not been granted safe passage, according to the UK envoy to the OPCW, Peter Wilson. The US expressed concerns that Russia may have tampered with evidence at the site.The OPCW team is tasked with determining whether banned substances were used in the attack, a charge that both Syria and its most powerful ally, Russia, have vehemently denied.Syria's Deputy Foreign Minister Fayssal Mikdad said Monday his country was ready to facilitate the OPCW team in any way to carry out its mission, the state-run SANA news agency reported, while Kremlin spokesman Dmitry Peskov did not respond directly to CNN's question on whether Russia had blocked the experts. Peskov said only that Russia was against "groundless" accusations about who was responsible for the attack.Russian Deputy Foreign Minister Sergei Ryabkov said the OPCW team's arrival was hampered by the weekend air strikes, state media RIA Novosti reported.The suspected chemical attack is the latest issue to heighten tensions between Russia and Western powers. More than 100 Russian diplomats were expelled from more than 20 countries in March over the poisoning of a Russian ex-spy on British soil, which the UK and US has blamed on the Russian government. Russia denies the accusations.Russian officials last week claimed British intelligence agencies had helped stage the suspected chemical attack in Douma."Yet again, Russia is spreading conspiracy theories and misinformation designed to undermine the integrity of the OPCW's fact finding mission," Wilson said in a statement."A significant body of information, including intelligence, indicates the Syrian regime is responsible for this latest attack."The US envoy to the OPCW, Kenneth D. Ward, said he was concerned that Russia may have interfered with the site of the Douma attack."We are concerned they may have tampered with it with the intent of thwarting the efforts of the OPCW Fact Finding Mission to conduct an effective investigation. This raises serious questions about the ability of the (team) to do its job," he said in a statement Monday.Russian Foreign Minister Sergey Lavrov said last week his country had sent experts to the site and found "no trace" of chemical weapons use. On Monday, he told the BBC's Hardtalk show that he guaranteed there had been no Russian tampering.Around 75 people, including children, were killed in the Douma assault, UK officials have said, while 500 people were treated in the attack's aftermath with symptoms consistent with chemical weapons exposure, the World Health Organization reported, citing its partners on the ground.The OPCW has recorded more than 390 allegations of chemical weapons use in Syria since its investigation began in 2014, Wilson said. 3222

The White House on Wednesday downplayed comments by national security adviser John Bolton, who recently invoked Libya's decision to denuclearize during the Bush administration as a model for US policy on North Korea, potentially placing a planned US-North Korea summit in jeopardy.Hours earlier, a North Korean official said Bolton's remarks were indicative of an "awfully sinister move" to imperil the Kim regime. North Korea stunned Washington on Tuesday by threatening to abandon talks between President Donald Trump and Kim Jong Un if Washington insists on pushing it "into a corner" on nuclear disarmament.Referring to the Libya comparison, White House press secretary Sarah Sanders said Wednesday that she hadn't "seen that as part of any discussions so I'm not aware that that's a model that we're using."I haven't seen that that's a specific thing. I know that that comment was made. There's not a cookie cutter model on how this would work."She continued, "This is the President Trump model. He's going to run this the way he sees fit. We're 100% confident, as we've said many times before, as I'm sure you're all aware, he's the best negotiator and we're very confident on that front."In April, Bolton suggested that the White House was looking at Libya as an example of how it will handle negotiations with North Korea to denuclearize."We have very much in mind the Libya model from 2003, 2004," Bolton said on Fox News. "There are obviously differences. The Libyan program was much smaller. But that was basically the agreement that we made."The US agreed to ease sanctions on Libya in 2003 in exchange for a promise by Moammar Gadhafi to abandon his country's nuclear program. Eight years later, however, Gadhafi was overthrown and killed by rebels backed by Washington.In a statement published late Tuesday by the state-run Korea Central News Agency, Kim Kye Gwan, North Korea's first vice minister of the Ministry of Foreign Affairs, called Bolton's comments indicative of "an awfully sinister move to impose on our dignified state the destiny of Libya or Iraq which had been collapsed due to yielding the whole of their countries to big powers.""It is absolutely absurd to dare compare (North Korea), a nuclear weapon state, to Libya which had been at the initial stage of nuclear development," Kim said. "(The) world knows too well that our country is neither Libya nor Iraq which have met miserable fate."Singling out the national security adviser for personal criticism, Kim said that North Korea had "shed light on the quality of (John) Bolton already in the past, and we do not hide our feeling of repugnance towards him."  2657

The United Kingdom says it will be the first to conduct COVID-19 vaccine human challenge trials.It's different than other vaccine studies. People will be deliberately infected with the virus, which speeds up the research process.Pending approval, the process will start in January at a London hospital. It will require about 90 healthy young adults between the ages of 18 and 30.The group 1 Day Sooner has recruited from all over the world, including 3,000 Britons.“If the vaccine works, then ideally, people don't get infected and if people do, then they will be closely monitored and treated, but because these are young and healthy people taking part in the trial, I think, researchers feel comfortable doing so because the risks of death are on par with something like kidney donation for people who are young and healthy,” said Abie Rohrig with 1 Day Sooner.Before researchers test the vaccine, they'll do a characterization study. That's where volunteers are infected by getting a vaccine to determine the right amount of virus to give during the trial.Because of the risk, 1 Day Sooner is advocating for the entire process to be made public.Results could come in May. Even though that's likely after other COVID-19 vaccines are licensed, it's still important because we need billions of doses and because of the unique data human challenge trials provide.“Researchers can understand how the virus works in the human body. They can understand the biological markers of immunity. In fact, much of our understanding of other types of coronaviruses come from challenge studies that were conducted in the 1960s in Britain,” said Rohrig.Human challenge volunteers are paid and monitored for at least a year after. 1722

The Twitter account that once belonged to former Republican presidential candidate Herman Cain tweeted Sunday evening that new CDC info indicated that COVID-19 "isn't as deadly" as once thought — despite the fact that Cain himself died of the virus just weeks ago.Cain died of COVID-19 on July 30 — four weeks after his office announced that he had been hospitalized in connection with the disease.On Aug. 11, Cain's daughter said in an update on his website that his family and campaign staff would continue to post content on the web and operate under the moniker "The Cain Gang.""He would have wanted us to do this. And that's exactly what we're going to do," Cain's daughter, Dr. Melanie Cain Gallo, wrote on HermanCain.com.In the weeks since the announcement, Cain's Twitter account has actively been sharing news links from largely conservative-leaning news outlets. On Sunday evening, the account tweeted a link to a story about a recent CDC announcement stating that COVID-19 was only listed as the sole cause of death for 6% of those killed by the virus."It looks like the virus is not as deadly as the mainstream media first made it out to be," the "Cain Gang" wrote on Twitter. 1196

The shape of the Earth is a spheroid, right? A YouGov study conducted this year says a third of people ages 18-24 aren’t sure our planet is round."If you believe we live on a globe, I know you're deceived." Welcome to the Flat Earth International Conference. “NASA has obviously lied to us on numerous occasions,” says Wendell, a conference attendee.Most of the people gathered at the conference held in Denver, Colorado believe Americans live on a lie. The flat Earth believers think pictures of the earth are fake and astronauts are actors. Social media sites like YouTube have made the flat earth theory more available in recent years. Some of those accounts have tens of thousands of followers."If you do trust your senses, you're seeing things different than what you're being fed," says Debra Auden, who traveled from Texas to the conference.Dr. Ka Chun Yu, the curator of space science at the Denver Museum of Nature and Science, says he was really surprised when he heard about the number of flat-earthers."We've known for over 2,000 years that the earth is more or less a sphere, a ball or a round shape."This is how the Greeks knew the earth was round. They realized that if you had sticks in the ground and you were able to measure their shadows on the same day, the lengths of the shadows would actually be different," Dr. Yu says.But to flat-earthers, science's facts are fiction. Flat Earth believers say an ice wall keeps us from falling off the surface.So, why do flat-earthers believe there would be such a lie about a round Earth? Some say conspiracy, while others turn to God. "You might not be convinced, but I encourage you to visit your local science museum or planetarium," Dr. Yu says. 1752
