New coronavirus losing potency, top Italian doctor says

Washington, Jan 9: The U.S. and Iran stepped back from the brink of possible war Wednesday as President Donald Trump signaled he would not retaliate militarily for Iran's missile strikes on Iraqi bases housing U.S. troops. No one was harmed in the strikes, but U.S. forces in the region remained on high alert.

Speaking from the White House, Trump seemed intent on deescalating the crisis, which spiralled after he authorized the assassination of Iran's top general, Qassem Soleimani. Iran responded overnight by firing more than a dozen missiles at two installations in Iraq, its most direct assault on America since the 1979 seizure of the U.S. Embassy in Tehran.

Trump's takeaway was that “Iran appears to be standing down, which is a good thing for all parties concerned and a very good thing for the world.”

The region remained on edge, however, and American troops including a quick-reaction force dispatched over the weekend were on high alert. Hours after Trump spoke, an ‘incoming’ siren went off in Baghdad's Green Zone after what seemed to be small rockets “impacted” the diplomatic area, a Western official said. There were no reports of casualties.

Iran's Supreme Leader Ayatollah Ali Khamenei said the overnight strike was not necessarily the totality of Iran's response. “Last night they received a slap,” Khamenei said. “These military actions are not sufficient (for revenge). What is important is that the corrupt presence of America in this region comes to an end.”

The strikes had pushed Tehran and Washington perilously close to all-out conflict and left the world waiting to see whether the American president would respond with more military force. Trump, in his nine-minute, televised address, spoke of a robust U.S. military with missiles that are “big, powerful, accurate, lethal and fast.'' But then he added: “We do not want to use it."

Iran for days had been promising to respond forcefully to Soleimani's killing, but its limited strike on two bases--one in the northern Iraqi city of Irbil and the other at Ain al-Asad in western Iraq--appeared to signal that it too was uninterested in a wider clash with the U.S. Foreign minister Mohammad Javad Zarif tweeted that the country had “concluded proportionate measures in self-defence.”

Trump said the U.S. was “ready to embrace peace with all who seek it.” That marked a sharp change in tone from his warning a day earlier that “if Iran does anything that they shouldn't be doing, they're going to be suffering the consequences, and very strongly.”

Trump opened his remarks at the White House by reiterating his promise that “Iran will never be allowed to have a nuclear weapon.” Iran had announced in the wake of Soleimani's killing that it would no longer comply with any of the limits on uranium enrichment in the 2015 nuclear deal crafted to keep it from building a nuclear device.

The president, who had earlier pulled the U.S. out of the deal, seized on the moment of calm to call for negotiations toward a new agreement that would do more to limit Iran's ballistic missile programmes and constrain regional proxy campaigns like those led by Soleimani.

Trump spoke of new sanctions on Iran, but it was not immediately clear what those would be.

Washington, Jun 6: Washington mayor Muriel Bowser on Friday renamed an area near the White House that has become the epicenter of anti-racism protests over the past week "Black Lives Matter Plaza" -- unveiling a giant street mural.

But in so doing, the African-American mayor piqued the ire of the very movement she was supporting, as well as of President Donald Trump.

The protests are focused on the May 25 death in Minneapolis of 46-year-old black man George Floyd while in police custody. A white officer kneeled on his neck until he lost consciousness.

That officer and three others are now in custody and facing charges -- second-degree murder for the kneeling officer, and aiding and abetting that crime for his colleagues.

Just north of the White House, the words BLACK LIVES MATTER were painted in huge yellow letters along the street leading to the presidential mansion, along with the symbol from the DC flag.

"The section of 16th street in front of the White House is now officially 'Black Lives Matter Plaza'," Bowser tweeted.

A city worker put up a new street sign with the name.

"Determination to make America the land it ought to be," she said on Twitter.

The corner of 16th and H is significant -- in a controversial incident on Monday, peaceful protesters gathered there were dispersed with tear gas.

Shortly afterwards, Trump walked from the White House to a nearby church for a photo op, during which he held the Bible in his hand.

"There was a dispute this week about whose street this is. Mayor Bowser wanted to make it abundantly clear that this is DC's street and to honor demonstrators" who protested on Monday, her chief of staff John Falcicchio tweeted.

Rose Jaffe, one of the artists in the collective that painted the BLACK LIVES MATTER sign, told AFP it was "about reclaiming the streets of DC."

But she added that Bowser "has to do more than just a photo-op -- she must carry on when this is washed away" on issues like police accountability.

Stars Like LeBron James praised her move on Twitter, but the local chapter of the Black Lives Movement balked, calling the mural a "performative distraction from real policy changes."

"This is to appease white liberals while ignoring our demands," it said on Twitter, saying Bowser had "consistently been on the wrong side" of the movement.

'We are well equipped'

The US government deployed a significant contingent of federal officers and National Guard troops from other states -- many of them not wearing any identifying garb or badges -- to handle protests in Washington.

Bowser had called up the local Guardsmen but the Justice Department moved to take partial control of peacekeeping, with Guard troops from as far away as Utah brought in.

In a letter to Trump dated Thursday and tweeted early Friday, Bowser called for "all extraordinary federal law enforcement and military presence" to be removed.

She said their deployment was "inflaming demonstrators and adding to the grievances of those who, by and large, are peacefully protesting for change and for reforms to the racist and broken systems that are killing black Americans."

"These additional, unidentified units are operating outside of established chains of command," she added.

"We are well equipped to handle large demonstrations and First Amendment activities," including the right to assemble, Bowser said.

Trump reiterated on Friday that authorities need to "dominate the streets," and has been unapologetic about the deployment of forces.

And on Twitter, he lashed out at Bowser, calling her "incompetent" and saying the National Guard had saved her from "great embarrassment."

Senator Mike Lee of Utah accused Bowser of evicting Utah National Guard members from area hotels.

She replied: "DC residents cannot pay their hotel bills. The Army can clear that up with the hotel today, and we are willing to help."

Washington, May 19: As the scientists across the world are struggling to develop a vaccine for combating coronavirus, US drugmaker Moderna announced on Monday (local time) that the phase I trial of its Covid-19 vaccine has shown positive early results.

The company is hopeful that it's vaccine could be available to the public as early as January next year. Several firms across the world are in the race to develop a vaccine for the deadly virus which has claimed over 3 lakh lives worldwide.

CNN citing Dr. Tal Zaks, Moderna's chief medical officer reported that "if future studies go well, the company's vaccine could be available to the public as early as January".

"This is absolutely good news and news that we think many have been waiting for for quite some time," Zaks was quoted as saying.

Moderna, based in Cambridge, Massachusetts announced that the vaccine developed neutralising antibodies to the virus at levels reaching or exceeding the levels seen in people who have naturally recovered from Covid-19, reported CNN.

These will be followed by phase 2 trials and phase 3 trials, which Moderna plans to start in July.

President Donald Trump had on Friday said that that the United States will be able to deliver a few hundred million doses of COVID-19 vaccine, under 'Operation Warp Speed', by the end of this year.

"I have very recently seen early data from a clinical trial with a coronavirus vaccine and this data made me feel even more confident that we'll be able to deliver a few hundred million doses of vaccine by the end of 2020 and we will do the best we can," Trump had said at a press conference at the White House on Friday.
