Indian peacekeepers prevented more casualties in S Sudan: UN official

Ottawa, Jun 25: Prime Minister Justin Trudeau took his son out for ice cream on Wednesday in his first family outing since Canada started easing out of its pandemic lockdown.

It was also Saint-Jean-Baptiste Day in Quebec province.

Wearing masks, the Canadian leader and his six-year-old son Hadrien were cheered at Chocolats Favoris in Gatineau, Quebec.

According to a pool report, Trudeau said the shop tapped into a federal emergency wage subsidy and business loan in order to weather the pandemic, and "avoid being frozen out of the frozen treat market."

Hadrien is said to have bounced with excitement, settling on a vanilla cone with a cookie topping while dad bought a vanilla cone dipped in chocolate for himself.

Father and son then headed out to the patio, where they doffed their masks to eat their cones.

Canada's provinces and territories declared states of emergency mid-March, closing schools and non-essential businesses in response to the pandemic.

Italian researchers have claimed that they have successfully developed a vaccine to contain coronavirus (COVID-19) which is likely to work on humans, a report said.

Luigi Aurisicchio, CEO of Takis, the firm developing the medication, said that a coronavirus candidate vaccine has neutralised the virus in human cells for the first time, the Arab News reported.

"This is the most advanced stage of testing of a candidate vaccine created in Italy. Human tests are expected after this summer," Aurisicchio was quoted as saying to Italian news agency ANSA.

"According to the Spallanzani Hospital, as far as we know we are the first in the world so far to have demonstrated neutralisation of the coronavirus by a vaccine. We expect this to happen in humans too," he added.

The researchers experimented with the vaccine on mice that had successfully developed antibodies that blocked the virus from infecting the cells. They further observed that the five vaccine candidates generated a large number of antibodies, and selected two with the best results.

All of the vaccine candidates currently being developed are based on the genetic material of DNA protein "spike", the molecular tip used by the coronavirus to enter human cells.

They are injected with the so-called "electroporation" technique, which consists of an intramuscular injection followed by a brief electrical impulse, helping the vaccine break into the cells and activating the immune system, the report said.

Researchers believe that this makes their vaccine particularly effective for generating functional antibodies against the "spike" protein, in particular in the lung cells, which are the most vulnerable to coronavirus.

"We are working hard for a vaccine coming from Italian research, with an all-Italian and innovative technology, tested in Italy and made available to everyone," Aurisicchio was quoted by the Arab News report.

"In order to reach this goal, we need the support of national and international institutions and partners who may help us speed up the process," he noted.

The total number of COVID-19 infections, fatalities and recoveries since the pandemic began has risen to 213,013 in the country.

Washington, May 28: US President Donald Trump has warned social media giants that his government could "strongly regulate" or "close them down" after Twitter fact-checked one of his tweets for the first time.

"Republicans feel that Social Media Platforms totally silence conservatives voices," Xinhua news agency reported citing Trump as saying in a tweet to his 80 million followers on Wednesday.

"We will strongly regulate, or close them down, before we can ever allow this to happen."

Later in the day, he said that Twitter "has now shown everything we have been saying about them... is correct" and vowed "big action to follow".

The President's remarks came after Twitter slapped a warning label on one of his tweets on Tuesday, cautioning readers "Trump makes unsubstantiated claim that mail-in ballots will lead to voter fraud".

It was in response to Trump's tweet, without providing evidence, said: "There is NO WAY (ZERO!) that Mail-In Ballots will be anything less than substantially fraudulent."

It is unclear what regulatory steps the president could take without new laws passed by Congress, the BBC reported.

The White House is yet to offer further details.

Earlier, Trump has accused Twitter of interfering in this year's US presidential election scheduled for November, saying the company was "completely stifling free speech, and I, as president, will not allow it to happen".

With more than 52,000 tweets currently to his name, Trump is a prolific tweeter and relies on the platform to disseminate his views to millions of people.

He has used Twitter to launch attacks on opponents, with targets ranging from North Korean leader Kim Jong-un to his political rivals in the US.

In 2017 he used anti-Muslim tweets aimed at London Mayor Sadiq Khan to serve a domestic political purpose of warning about immigration.
