Canadian minister asked to take off turban at US airport

Hong Kong, Jun 10: The Hong Kong police on Wednesday said they had arrested 53 people during demonstrations on Tuesday evening which were called to mark the one-year anniversary of the protest against a bill proposing extraditions to mainland China. That protest grew into a pro-democracy movement and sparked seven months of protests against Beijing's rule.

Hundreds of activists took to the streets in Hong Kong yesterday, at times blocking roads in the heart of the city, before police fired pepper spray to disperse crowds, Al Jazeera reported.

The police informed that 36 males and 17 females were arrested for offenses including unlawful assembly and disorderly conduct.

Protesters had defied a ban on gatherings of more than eight people introduced by the Hong Kong government to prevent the spread of the coronavirus.

"Lawful protests are always respected, but unlawful acts are to be rejected. Please stop breaking the law," police said in a tweet.

More protests are being planned in the coming days, with pro-democracy supporters fearing the proposed national security legislation will stifle freedoms in the city.

While details of the security law or how it will operate have yet to be revealed, authorities in Beijing and Hong Kong have said there is no cause for concern and the legislation will target a minority of "troublemakers".

But critics say the law would destroy the civil liberties Hong Kong residents enjoy under the "one country, two systems" agreement put in place when the United Kingdom handed the territory back to China in 1997. The agreement is set to end in 2047.

Japan had already issued a statement independently expressing serious concern about Beijing's move on May 28, the day China approved the decision and called in the Chinese ambassador to convey its view.

The United States, Britain, Australia, and Canada also condemned the move, with Washington saying it would revoke Hong Kong's special trading status granted under a 1992 law on the condition that the city retains key freedoms and autonomy.

China blames the protests in part on foreign intervention and is rushing to enact the national security law aimed at curbing secessionist and subversive activities in Hong Kong.

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.

Nairobi, Mar 14: Kenya and Ethiopia on Friday announced their first confirmed cases of coronavirus, as East Africa, which has so far been unscathed by the global pandemic, scaled up emergency measures to contain its spread.

In Kenya, a 27-year-old Kenyan woman tested positive for the virus on Thursday in Nairobi, a week after returning from the United States via London.

She was in a stable condition and recovering, Health Minister Mutahi Kagwe told reporters.

"We wish to assure all Kenyans that the government will use all the resources available to fight coronavirus," he said, as the government rolled out a raft of new containment measures.

The government had traced all the contacts of the patient since she arrived back in Kenya on March 5, he said.

"At the moment, there is absolutely no need for panic and worry," he said.

Kenya, with a population of 50 million people, saw a spree of panic buying among the middle-class in Nairobi supermarkets, in the wake of the announcement.

Meanwhile Ethiopia, Africa's second most populous nation with over 100 million people, said a 48-year-old Japanese man who had arrived in the country on March 4 from Burkina Faso was confirmed to have contracted the virus.

"He is undergoing medical follow-up and is in a stable condition. Those who have been in contact with this person are being traced and quarantined," the health ministry said in a statement.

Burkina Faso only confirmed its first case on Tuesday -- a couple returning from France -- and the Japanese patient had been in that country since February 24.

Ethiopian Health Minister Lia Tadesse said three other patients were in isolation.

Ethiopia becomes the 15 country in Africa with a confirmed case of the virus that has swept the globe, infecting more than 130,000 people and killing nearly 5,000 since it first emerged in China.

But to date the continent has been spared the worst of the pandemic.

Only five people have succumbed to coronavirus so far -- all in north Africa -- with the sub-Saharan region recording no deaths and very low numbers of confirmed cases.

But countries in East Africa -- which until the positive case in Kenya, had only recorded negative test results -- have been taking precautions.

Some flights have been restricted, with Kenya Airways suspending its route to Rome, and charter flights from Italy to the Kenyan coast on hold.

It has also suspended international conferences, a top earner in Nairobi, a hub for such events in the region, and non-essential travel abroad for politicians.

The government announced more expansive restrictions on Friday, including a temporary ban on major public gatherings, prison visits and activities between schools.

Other countries in the region have been rolling out their own measures.

In Rwanda, which shares a border with the Democratic Republic of Congo, which has confirmed cases, washing basins with soap and sanitiser have been placed on streets for commuters to use before boarding buses.

Authorities in Kigali, the capital, have also banned concerts, rallies and trade fairs -- although like in Kenya and Uganda, church services have been proceeding and bars, restaurants and entertainment precincts remain open.

Neighbouring Burundi, meanwhile, has quarantined 34 people in a hotel in Bujumbura as a precaution.

Uganda has ordered that visitors from a number of affected countries self quarantine for 14 days, or consider simply not visiting at all.

South Sudan's health ministry said meanwhile that it was "temporarily suspending direct flights between South Sudan and all affected countries".

Kagwe, the Kenyan health minister, also addressed a rumour circulating on social media that people with black skin cannot contract the virus.

"I would like to disabuse that notion. The lady (confirmed with coronavirus in Kenya) is an African, like you and I," he said.
