'Wasn't kidding,' says Trump as US begins designing Mexican border wall

Washington, Jun 24: Twitter has once again flagged a tweet from US President Donald Trump which promoted violence by saying if protesters tried to set up an "autonomous zone" in Washington, DC they would be met with "serious force".

This is the fourth time Twitter has red flagged Trump's tweet for glorifying violence or violating its policies.

Trump has been critical of the "autonomous zone" in Seattle, an area occupied by protestors for much of this month.

"We've placed a public interest notice on this Tweet for violating our policy against abusive behaviour, specifically, the presence of a threat of harm against an identifiable group," Twitter's safety team tweeted late Tuesday.

Trump had tweeted: "There will never be an ‘Autonomous Zone' in Washington, D.C., as long as I'm your President. If they try they will be met with serious force!"

Twitter earlier labeled a video tweeted by him which mocked CNN as manipulated media.

According to Twitter, "this Tweet has been labeled per our synthetic and manipulated media policy to give people more context".

In May, Twitter labeled two Trump tweets that made false claims about mail-in ballots in California.

Twitter later labeled another Trump tweet glorifying violence in which he said, "when the looting starts, the shooting starts."

Facebook also removed a Trump campaign ad featuring a symbol used by Nazis for political dissenters, saying the ad violated its policies.

Beijing/Zurich, Mar 4: China has approved the use of Swiss drugmaker Roche's anti-inflammation drug Actemra for patients who develop severe complications from the coronavirus as it urgently hunts for new ways to combat the deadly infection that is spreading worldwide.

China is hoping that some older drugs could stop severe cytokine release syndrome (CRS), or cytokine storms, an overreaction of the immune system which is considered a major factor behind catastrophic organ failure and death in some coronavirus patients.

Actemra, a biologic drug approved in 2010 in the United States for rheumatoid arthritis (RA), inhibits high Interleukin 6 (IL-6) protein levels that drive some inflammatory diseases.

China's National Health Commission said in treatment guidelines published online on Wednesday that Actemra can now be used to treat coronavirus patients with serious lung damage and high IL-6 levels.

Separately, researchers in the country are testing Actemra, known generically as tocilizumab, in a clinical trial expected to include 188 coronavirus patients and running until May 10.

Roche, which donated 14 million yuan ($2.02 million) worth of Actemra during February, said the trial was initiated independently by a third party with the aim of exploring the efficacy and safety of the drug in coronavirus patients with CRS.

It added that there was currently no published clinical trial data on the drug's safety or efficacy against the virus.

More than 3,000 people have died and 93,000 have been infected by the novel coronavirus thought to have originated in Wuhan, China, before spreading to around 90 countries including the United States, Italy, Switzerland, France and Germany.

The Swiss company, for which China is its No. 2 market behind the United States, also makes diagnostic gear to detect the coronavirus.

Since Actemra's approval a decade ago, it has become a go-to drug against other inflammatory conditions, including cytokine storms in cancer patients receiving cell therapies from Novartis and Gilead Sciences.

In 2012 it helped save the life of a young U.S. girl, the first child to be treated for leukaemia with Novatis' Kymriah, from a post-treatment rush of IL-6.

Priced at between $20-30,000 annually for RA according to SSR Health, Roche's medicine is also used for rare juvenile arthritis and giant cell arteritis, or inflammation of the blood vessels.

Beijing, Jan 21: The Chinese official investigating a pneumonia outbreak stemming from a new coronavirus said the disease can spread from person to person but can be halted with increased vigilance, as authorities on Tuesday confirmed a fourth death.

Zhong Nanshan said there was no danger of a repeat of the Severe Acute Respiratory Syndrome (SARS) epidemic that killed nearly 800 people globally during a 2002-2003 outbreak, which started in China, as long as precautions were taken.

"It took only two weeks to identify the novel coronavirus," state news agency Xinhua quoted Zhong as saying late on Monday.

The outbreak was still in its early stages and China had good surveillance and quarantine systems to help control it, he added.

The outbreak has spread from the central city of Wuhan to cities including Beijing and Shanghai, with more than 200 cases reported so far. Four cases have been reported outside China - in South Korea, Thailand and Japan.

Australia on Tuesday said it would screen passengers on flights from Wuhan amid rising concerns that the virus will spread globally as Chinese travellers take flights abroad for the Lunar New Year holiday starting this week.

Authorities around the globe, including in the United States and many Asian countries, have stepped up screening of travellers from Wuhan.

Chinese authorities confirmed a total of 217 cases of the virus in China as of 6 p.m. (1000 GMT) on Monday, state television reported, 198 of which were in Wuhan.

A fourth person died on Jan. 19, the Wuhan Municipal Health Commission said. The 89-year-old man, who had underlying health diseases including coronary heart disease, developed symptoms on Jan. 13 and was admitted to hospital five days later, it added.

Zhong, who is renowned in China for his work fighting SARS in 2003, confirmed that the virus can pass from person-to-person.

Fifteen medical workers in Wuhan had been diagnosed with pneumonia, with one other suspected case, the Wuhan Municipal Health Commission said. Of the infected staff, one was in critical condition.

In Shanghai, officials on Tuesday confirmed a second case involving a 35-year-man who had visited Wuhan in early January, and said they were monitoring four other suspected cases.

The virus causes a type of pneumonia and belongs to the same family of coronaviruses as SARS. Symptoms include fever and difficulty in breathing, which are similar to many other respiratory diseases and pose complications for screening efforts.

The World Health Organisation (WHO) said on Monday an animal source appeared most likely to be the primary origin of the outbreak and that some "limited human-to-human transmission" occurred between close contacts.

The Geneva-based U.N. agency convened an emergency committee for Wednesday to assess whether the outbreak constitutes an international health emergency and what measures should be taken to manage it.

So far, the WHO has not recommended trade or travel restrictions, but a panel of independent experts could do so or make other recommendations to limit spread.
