Fake news surges after Sri Lanka attack

Colombo, May 22: Sri Lankan social networks saw a surge in fake news after the Easter suicide bombings a month ago despite an official social media blackout, highlighting the inability of governments to contain disinformation, experts said.

A nine-day ban on platforms including Facebook, Twitter, YouTube, Instagram and WhatsApp was introduced following the Islamic State-claimed attacks on churches and hotels on April 21 which killed 258 people and wounded nearly 500.

Many anxious social media users switched to virtual private networks (VPNs) or the TOR network to bypass the order and keep communication open with friends and relatives as the extent of the carnage became clear.

But for others, the tools were a means to spread confusion and vitriol as the island struggled to come to terms with one of the worst terror attacks in its history.

Sanjana Hattotuwa, who monitors social media for fake news at the Centre for Policy Alternatives in Colombo, said the government blackout had failed to prevent "engagement, production, sharing and discussion of Facebook content", and that he had seen a significant increase in false reports.

AFP has published half a dozen fact-checks debunking false claims made on Facebook and Twitter after the Easter attacks.

Some had dug out photos of coffins and funerals from Sri Lanka's brutal decades-long civil war and claimed they showed victims of the blasts.

One video posted to Facebook showed police arresting a man dressed in a burqa and claimed he was involved in the bombings. The video was actually from 2018, and showed a man who had used a burqa to hide his identity while he sought to attack someone over a debt issue.

Another used a five-year-old photo from India that showed a group of men wearing T-shirts with "ISIS", another name for Islamic State, written on them to claim there was an active IS cell in eastern Sri Lanka.

One Twitter user claiming to be a high-ranking Sri Lankan army brigadier used the platform to accuse neighbouring India of being involved in the attacks. The account was later taken down by Twitter after the Sri Lankan army complained.

Authorities in Sri Lanka -- where ethnic divisions still linger after decades of war -- previously blocked Facebook in March 2018 after Buddhist hardliners used incendiary posts to fan religious violence that left three people dead and reduced several hundred homes and shops to ashes.

The surge in fake news has further blemished the troubled reputation of social media -- which several years ago had been seen as a means to expand freedom of information -- in the region.

In India, authorities have temporarily shut down mobile networks or blocked social media apps during riots, while critics say the spread of hate speech via Facebook was crucial in facilitating a brutal 2017 military crackdown on the Rohingya Muslim minority in Myanmar.

Since the attacks, Sri Lankan authorities have imposed other short bans on social media, including earlier this month after mobs in the northwestern town of Chilaw attacked Muslim-owned businesses in anger at a Facebook post by a shopkeeper.

But for those unaware of the government ban or unable to circumvent it, the blocking of social media in the days following the attacks was a cause for panic.

A Sydney-based engineer was desperate to call his sister in Colombo soon after hearing about the Easter blasts, but could not get through.

"I kept calling her on WhatsApp, but there was no reply. We are so used to calling on WhatsApp, I had forgotten her landline number," the Sri Lankan-born engineer said.

Fortunately, he said, he managed to call a friend in Colombo who was using a VPN to access WhatsApp and told him about the social media ban that prevented him from reaching his sister.

Wuhan, Feb 16: The death toll from China's coronavirus epidemic has climbed to 1,665 after 142 more people died, mostly in the worst-hit Hubei Province, and the confirmed cases jumped to 68,500, officials said on Sunday, as top WHO experts scramble to assist Beijing contain the virus spread.

China's National Health Commission confirmed 2,009 new cases across the country.

Hubei and its provincial capital Wuhan, where the virus first emerged in December, reported 1,843 of the new cases. The latest report brought the total confirmed cases in Hubei to 56,249 cases.

Of the new deaths, 139 were in Hubei, two in Sichuan, and one in Hunan, the state-run Xinhua news agency reported.

The number of new cases, however, appears to have started dropping and a top Chinese health official has said efforts to control the outbreak have reached the “most crucial stage".

The report said 9,419 infected patients had been discharged from hospital after recovery so far.

The coronavirus has posed a severe threat to the medical staff as more than 1,700 Chinese health officials have been infected by the virus while treating the patients and six of them have died.

Experts from the World Health Organisation are expected in Beijing on Sunday to join Chinese health authorities in containing the virus, which has spread to several other countries forcing them to temporarily stop tourist arrivals from China.

The health commission said a joint mission with WHO experts will pay field visits to China's three provincial-level regions to learn the effectiveness of the epidemic control measures.

One task of the mission will be to come up with standard medicine to cure the disease, according to the health commission.

Several antiviral drugs are under clinical trials and Chinese researchers have narrowed down their focus to a few existing drugs, including Chloroquine Phosphate, Favipiravir and Remdesivir, said Zhang Xinmin, director of the China National Centre for Biotechnology Development.

Experts have asked people to frequently wash hands and face, and wear masks.

Authorities have begun quarantining large quantity of bank notes and coins in the affected areas and sanitising them with UV light before releasing them back into circulation to stop the virus from spreading.

Canadian researchers are developing a DNA vaccine for SARS-CoV-2, the coronavirus that causes COVID-19 and has currently infected nearly 5,00,000 people worldwide and crippled the global economy.

Entos Pharmaceuticals, a health-care biotechnology company headed by a University of Alberta researchers, develop new therapeutic compounds using the company's proprietary drug-delivery platform and has begun manufacturing vaccine candidates against the novel coronavirus.

"Given the urgency of the situation, we can have a lead candidate vaccine within two months. Once we have that it's a race to get it into clinical trials," said John Lewis, CEO of Entos and a Professor at the University of Alberta in Canada.

Lewis said in comparison to a traditional vaccine, DNA-based vaccines hold several advantages.

Nucleic acids are introduced directly into the patient's own cells, causing them to make pieces of the virus--tricking the immune system into mounting a response without the full virus actually being present, the researcher said.

According to the company, the approach is recognised as being easier to move into large-scale manufacturing, offers improved vaccine stability and works without needing an infectious agent.

In the current absence of a vaccine for COVID-19, several companies around the world are mounting efforts to begin similar work.

The first clinical trial using a DNA-based vaccine developed by Moderna Inc.in the US on March 13.

Their approach allows for antibodies to be made in the human trial volunteers against a specific protein on the surface of the coronavirus that lets the virus enter human cells.

The hope is that the antibodies will stop the interaction.

Though this approach is designed to be effective against COVID-19 specifically, Lewis said Entos is taking a different tack.

The company plans to use plasmid DNA to amplify the production of key coronavirus surface and structural proteins with each injection, with an eye to the bigger picture.

"Many of the structural proteins in the virus are pretty well conserved across all the coronaviruses, including SARS and MERS," said Lewis.

"We're hoping that if we express more of the structural proteins that are common to most coronaviruses, we can inhibit the current COVID-19, and also potentially protect against all coronaviruses both past and future," Lewis added.

To move the project forward quickly, the company is seeking financial support from both provincial and federal levels of government.

"We have the opportunity to save a lot of lives, and I think it's really upon us and governments to find solutions for that," Lewis said.
