At least 24 killed, 42 wounded in Kabul bombing

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.

Houston, Mar 15: Researchers, studying the novel coronavirus, have found that the time between cases in a chain of transmission is less than a week, and over 10 per cent of patients are infected by someone who has the virus, but does not show symptoms yet, a finding that may help public health officials contain the pandemic.

The study, published in the journal Emerging Infectious Diseases, estimated what's called the serial interval of the coronavirus by measuring the time it takes for symptoms to appear in two people with the virus -- the person who infects another, and the infected second person.

According to the researchers, including those from the University of Texas at Austin, the average serial interval for the novel coronavirus in China was approximately four days.

They said the speed of an epidemic depends on two things -- how many people each case infects, and how long it takes cases to spread.

The first quantity, the scientists said, is called the reproduction number, and the second is the serial interval.

Due to the short serial interval of the disease caused by the coronavirus -- COVID-19 -- they said, emerging outbreaks will grow quickly, and could be difficult to stop.

“Ebola, with a serial interval of several weeks, is much easier to contain than influenza, with a serial interval of only a few days,” said Lauren Ancel Meyers, study co-author from UT Austin.

Meyers explained that public health responders to Ebola outbreaks have much more time to identify and isolate cases before they infect others.

“The data suggest that this coronavirus may spread like the flu. That means we need to move quickly and aggressively to curb the emerging threat,” Meyers added.

In the study, the scientists examined more than 450 infection case reports from 93 cities in China, and found the strongest evidence yet that people without symptoms must be transmitting the virus -- known as pre-symptomatic transmission.

More than one in ten infections were from people who had the virus but did not yet feel sick, the scientists said.

While researchers across the globe had some uncertainty until now about asymptomatic transmission with the coronavirus, the new evidence could provide guidance to public health officials on how to contain the spread of the disease.

“This provides evidence that extensive control measures including isolation, quarantine, school closures, travel restrictions and cancellation of mass gatherings may be warranted,” Meyers said.

The researchers cautioned that asymptomatic transmission makes containment more difficult.

With hundreds of new cases emerging around the world every day, the scientists said, the data may offer a different picture over time.

They said infection case reports are based on people's memories of where they went and whom they had contact with, and if health officials move quickly to isolate patients, that may also skew the data.

“Our findings are corroborated by instances of silent transmission and rising case counts in hundreds of cities worldwide. This tells us that COVID-19 outbreaks can be elusive and require extreme measures,” Meyers said.

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."
