You know it, I know it, they know it: Trump on China's Covid-19 death toll

Bueno Aires, Apr 25: Dozens of prisoners at a jail in Argentina's capital Buenos Aires rioted on Friday demanding urgent health measures after confirmation of a coronavirus case inside the facility.

Police surrounded the prison, which holds around 2,200 inmates, as explosions were heard, news agency reporters at the scene said.

A group of prisoners managed to climb onto a roof, burn mattresses and throw objects at security guards trying to quell the uprising.

Authorities have yet to comment on the riot or whether there are any injuries.

Inmates could be heard shouting demands for a judge to hear their case and for better protection against the pandemic, just a few days after a warden at the Villa Devoto prison was confirmed to have contracted the novel coronavirus.

"COVID-19 in Devoto, genocidal judges," read a banner hung from the prison roof. "We refuse to die in prison," read another.

The inmates are demanding, among other things, that releases that were pending before the pandemic be processed.

Several other riots broke out in prisons last week, including in Florencio Varela in Buenos Aires province where one inmate died and 20 were injured.

Argentina has been in lockdown since March 20 and has recorded more than 3,400 coronavirus cases and 167 deaths.

Moscow, Jan 16: Russia's government resigned in a shock announcement on Wednesday after President Vladimir Putin proposed a series of constitutional reforms.

In a televised meeting with the Russian president, Prime Minister Dmitry Medvedev said the proposals would make significant changes to the country's balance of power and so "the government in its current form has resigned".

"We should provide the president of our country with the possibility to take all the necessary measures" to carry out the changes, Medvedev said.

"All further decisions will be taken by the president." Putin asked Medvedev, his longtime ally, to continue as head of government until a new government has been appointed.

"I want to thank you for everything that has been done, to express satisfaction with the results that have been achieved," Putin said.

"Not everything worked out, but everything never works out." He also proposed creating the post of deputy head of the Security Council, suggesting that Medvedev take on the position.

Earlier Wednesday Putin proposed a referendum on a package of reforms to Russia's constitution that would strengthen the role of parliament.

The changes would include giving parliament the power to choose the prime minister and senior cabinet members, instead of the president as in the current system.

Washington, May 12: The US Federal Bureau of Investigation and cybersecurity experts believe Chinese hackers are trying to steal research on developing a vaccine against coronavirus, two newspapers reported Monday.

The FBI and Department of Homeland Security are planning to release a warning about the Chinese hacking as governments and private firms race to develop a vaccine for COVID-19, the Wall Street Journal and New York Times reported.

The hackers are also targeting information and intellectual property on treatments and testing for COVID-19.

US officials alleged that the hackers are linked to the Chinese government, the reports say.

The official warning could come within days.

In Beijing Foreign Affairs ministry spokesman Zhao Lijian rejected the allegation, saying China firmly opposes all cyber attacks.

"We are leading the world in COVID-19 treatment and vaccine research. It is immoral to target China with rumors and slanders in the absence of any evidence," Zhao said.

Asked about the reports, President Donald Trump did not confirm them, but said: "What else is new with China? What else is new? Tell me. I'm not happy with China."

"We're watching it very closely," he added.

A US warning would add to a series of alerts and reports accusing government-backed hackers in Iran, North Korea, Russia and China of malicious activity related to the pandemic, from pumping out false news to targeting workers and scientists.

The New York Times said it could be a prelude to officially-sanctioned counterattacks by US agencies involved in cyber warfare, including the Pentagon's Cyber Command and the National Security Agency.

Last week in a joint message Britain and the United States warned of a rise in cyber attacks against health professionals involved in the coronavirus response by organised criminals "often linked with other state actors."

Britain's National Cyber Security Centre and the US Cybersecurity and Infrastructure Security Agency said they had detected large-scale "password spraying" tactics -- hackers trying to access accounts through commonly used passwords -- aimed at healthcare bodies and medical research organisations.
