PM Modi holds 'productive talks' with Thai counterpart

Huawei will be completely removed from the UK's 5G networks by the end of 2027, the UK government announced on Tuesday after a review by the country's National Cyber Security Centre (NCSC) on the impact of US sanctions against the Chinese telecommunications giant.

In the lead up to this complete removal of all Huawei kit from UK networks, there will be a total ban on the purchase of any new 5G kit after December 31, 2020.

The decision was taken at a meeting of the UK's National Security Council (NSC) chaired by Prime Minister Boris Johnson, in response to new US sanctions against the telecom major imposed in May which removed the firm's access to products which have been built based on US semiconductor technology.

5G will be transformative for our country, but only if we have confidence in the security and resilience of the infrastructure it is built upon, said Oliver Dowden, UK Secretary of State for Digital, Culture, Media and Sport (DCMS).

Following US sanctions against Huawei and updated technical advice from our cyber experts, the government has decided it necessary to ban Huawei from our 5G networks. No new kit is to be added from January 2021, and UK 5G networks will be Huawei free by the end of 2027. This decisive move provides the industry with the clarity and certainty it needs to get on with delivering 5G across the UK, he said.

The minister, who laid out the details of the UK's ban on Huawei in the House of Commons, said the government will now seek to legislate with a new Telecoms Security Bill to put in place the powers necessary to implement the tough new telecoms security framework.

By the time of the next election (2024) we will have implemented in law an irreversible path for the complete removal of Huawei equipment from our 5G networks, said Dowden.

The new law will give the government the national security powers to impose these new controls on high risk vendors and create extensive security duties on network operators to drive up standards, DCMS said.

Technical experts at the NCSC reviewed the consequences of the US sanctions and concluded that Huawei will need to do a major reconfiguration of its supply chain as it will no longer have access to the technology on which it currently relies and there are no alternatives which we have sufficient confidence in.

They found the new restrictions make it impossible to continue to guarantee the security of Huawei equipment in the future.

After a ban on the purchase of new Huawei kit for 5G from next year, the aim is to completely remove the Chinese vendor's influence on 5G networks across the UK by the end of 2027.

The DCMS said Tuesday's decision takes into account the UK's specific national circumstances and how the risks from these sanctions are manifested in the country.

The existing restrictions on Huawei in sensitive and critical parts of the network remain in place, it highlighted.

The DCMS said the US action also affects Huawei products used in the UK's full fibre broadband networks. However, the UK has managed Huawei's presence in the UK's fixed access networks since 2005 and we also need to avoid a situation where broadband operators are reliant on a single supplier for their equipment.

As a result, following security advice from experts, DCMS is advising full fibre operators to transition away from purchasing new Huawei equipment. A technical consultation will determine the transition timetable, but it is expect this period to last no longer than two years.

The government said its new approach strikes the right balance by recognising full fibre's established presence and supporting the connections that the public relies on, while fully addressing the security concerns.

It stressed that its new policy in relation to high risk vendors has not been designed around one company, one country or one threat but as an enduring and flexible policy that will enable the UK to manage the risks to the network, now and in the future.

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.

New Delhi, Jan 8: Iran will welcome any peace initiative by India for de-escalating its tensions with the US after the killing of Iranian military commander Qasem Soleimani, the Iranian envoy here said on Wednesday.

His comments come hours after Iran launched missile strikes against two US military bases in Iraq in retaliation to the killing of its top commander General Qassem Soleimani.

"India usually plays a very good role in (maintaining) peace in the world. At the same time, India belongs to this region. We welcome all initiatives from all countries, especially India as a good friend for us, to not allow escalation (of tensions)," Iranian Ambassador to India Ali Chegeni told reporters after a condolence meeting for Solemani at the country's embassy here.

"We are not for war, we are looking for peace and prosperity for everybody in this region. We welcome any Indian initiative or any project that can help peace and prosperity in this world," he said.

On the Iranian attack on US targets in Iraq, Chegeni said his country retaliated under its right to defend.

Amid spiralling US-Iran tensions over the killing of Soleimani, External Affairs Minister S Jaishankar on Sunday had a conversation with his Iranian counterpart Javad Zarif and US Secretary of State Mike Pompeo, voicing India's concerns over the escalation of tensions.
