The United Nations says one million refugees have fled Ukraine to neighbouring countries.
The exodus has taken place in just seven days. The Russian invasion began last Thursday.
As the BBC's Lewis Goodall points out: "The refugee crisis of 2015 involved 1.3 million. That's nearly been surpassed by the numbers from Ukraine in a week."
In a statement on Twitter, UN High Commissioner for Refugees Filippo Grandi pleaded for "guns to fall silent, so that life-saving humanitarian...
The Queen is back at work and has carried out two virtual engagements, Buckingham Palace has said.
After testing positive for COVID, the 95-year-old had to cancel a number of events last week.
The virtual audiences on Tuesday were carried out by video link from Windsor Castle with the ambassadors of Andorra and Chad. Palace aides say the Queen will also be taking part in some private engagements, reports the BBC.
Although Buckingham Palace officials are not giving...
The tech industry is playing down fears of widespread raw materials shortages as a result of the war in Ukraine, after reports that chipmakers would face a severe crunch.
Russia and Ukraine are key suppliers of neon, a gas used in the lasers that etch microscopic patterns onto tiny slivers of silicon. Russia also supplies palladium, which has several uses in electronic components.
The sector has already been hit hard by a shortage of components for chipmaking,...
President Putin has put Russia's nuclear forces on "special" alert, raising concerns around the world. Some analysts suggest his actions should probably be interpreted as a warning to other countries not to escalate their involvement in Ukraine, rather than signalling any desire to use nuclear weapons.
Nuclear weapons have existed for almost 80 years, and many countries see them as a deterrent that continues to guarantee their national security, the BBC reports.
All figures for nuclear weapons...
Published in Jama Network Open and led by researchers from the Doherty Institute and The George Institute, the study found the majority of randomized clinical trials for COVID-19 are being performed in high-income countries, thereby misrepresenting the global burden of the disease.
Professor Steven Tong, a Royal Melbourne Hospital infectious diseases clinician, co-lead of clinical research at the Doherty Institute, principal investigator of the AustralaSian COVID-19 Trial (ASCOT), and senior author on the paper, said the inequality could bring...

Let me begin with an admission. So many times, I've thought: "Putin would never do this." Then he goes and does it.
"He'd never annex Crimea, surely." He did.
"He'd never start a war in the Donbas." He did.
"He'd never launch a full-scale invasion of Ukraine." He has.
I've concluded that the phrase "would never do" doesn't apply to Vladimir Putin.
And that raises an uncomfortable question:
"He'd never press the nuclear button first. Would...
The European Union has announced that it intends to begin shipping arms to Ukraine, the first time in its history it has taken such a step.
Speaking at a press conference this afternoon, European Commission President Ursula von der Leyen said the move marked a "watershed moment."
She also announced a raft of new sanctions targeting Russia and Belarus, and a ban on Russia using European airspace.

The announcement that Russia has placed its nuclear forces on special alert evokes fearful resonances of the Cuban Missile Crisis of 1962 – the time when Washington and Moscow came closest to nuclear war.
In that case, both sides stepped back thanks to a combination of skilful diplomacy, brinkmanship, and fear of the consequences, writes Gordon Corera of the BBC.
But historical parallels are not always exact. At the moment, we are not at the same level...
Both SARS-CoV-1, the virus that caused the 2003 outbreak of Severe Acute Respiratory Syndrome (SARS), and SARS-CoV-2, which causes COVID-19, originate from a group of betacoronaviruses known as "subgroup 2b." Coronaviruses from this subgroup have been highlighted as having significant potential to cross from animal hosts to humans with deleterious consequences, COVID-19 being the most recent one.
A coronavirus enzyme called papain-like protease, or PLpro, is one of two proteases that are required for the...
Russian assaults on Ukraine capital Kyiv have been met with fierce resistance as the Ukrainian military says it fought off several attacks, the BBC reports.
The military said in a Facebook post early on Saturday that an army unit managed to repel Russian forces near its base on a major city street.
President Volodymyr Zelensky said: "The occupiers wanted to block the centre of our state... We broke their plan."
Meanwhile, fighting continues near several other Ukrainian...
