New restrictions to control the spread of coronavirus in Turkey will ban all vehicles entering Istanbul and 30 other cities. Only essential traffic, including goods and medical products, will be allowed in.

A curfew will also apply to those under-20 from midnight on Friday, and wearing a mask will be mandatory in crowded public places, grocery stores and workpaces.

The number of deaths from the virus rose to 425 on Friday, and the number of confirmed cases reached more than 20,000.

One of the US's largest manufacturers, 3M, says it has been ordered by the White House to stop shipping N95 masks - disposable masks which filter out at least 95% of airborne particles - to Canada and Latin America.

US officials estimate the country will need 300m masks a month, but only about 50m are currently being produced.

On Friday morning, the company urged the Trump administration to reconsider the order, which was made using the Defense Production Act, citing "significant humanitarian implications" and expressing concern that other countries might retaliate.

In his daily press briefing, Prime Minister Justin Trudeau said he was in contact with US officials and was trying to "make them understand".

“There are thousands of nurses in Windsor who work in Detroit every single day, and Americans depend on them. There are medical products and other essential goods that move across the border in both directions," he said.

“These are things Americans rely on and it would be a mistake to create blockages or reduce trade.”

A bus driver in Detroit, Michigan, who railed against a passenger who coughed without covering her mouth in an impassioned Facebook video has died from Covid-19, officials told CBS News.

Fifty-year-old Jason Hargrove posted the video on 21 March. He died on Wednesday, according to the drivers' union.

In the video, Mr Hargrove said he had felt "violated" by the woman, who coughed repeatedly on his bus, adding that bus drivers were "doing our job, trying to make an honest living, take care of our families" too.

"That lets me know that some folks don't care," Mr Hargrove said. "At some point in time, we've got to draw the line and say enough is enough. I feel violated."

Detroit Mayor Mike Duggan told reporters: "He knew his life was being put in jeopardy ... by someone who didn't take this seriously and now he's gone."

Researchers are working at breakneck speed to find a vaccine for this coronavirus.

Doctors are testing current anti-viral drugs, which are known to be safe to give to people, to see if they work.

The first human trials were announced in the US last month, while Australian scientists have begun injecting ferrets with two potential vaccines.

But would a vaccine protect everyone? Who would be given it? And will there be side effects?

Our Health and science correspondent James Gallagher has been trying to answer the key questions.

The Zandaam Holland America cruise ship has docked in Fort Lauderdale, Florida, and 14 critically ill passengers have been taken to local hospitals.

The Zandaam's other passengers were then allowed to leave after being screened by paramedics. Non-Floridians were transported directly to the airport.

Four people died due to the coronavirus during the ship's journey, and hundreds were sick. Chile, Argentina and Peru had refused to let the ship dock, prompting the voyage up to Florida.

The Zandaam's sister ship, the Rotterdam, has also docked in Fort Lauderdale. Passengers without symptoms were moved earlier from the Zandaam to the Rotterdam in an effort to contain the virus' spread.

Some incredibly sad news to bring you.

Ismail Mohamed Abdulwahab, 13, from Brixton in south London, died in hospital on Monday.

We speak to a psychologist about the habit at the centre of the coronavirus spread.

Footage posted on social media appears to show people cheering Capt Brett Crozier as he disembarks the USS Theodore Roosevelt.

Capt Crozier was relieved of his command of the vessel after saying the US Navy was not doing enough to halt a coronavirus outbreak on board.

A White House spokesman said people "will be administered a Covid-19 test to evaluate for pre-symptomatic or asymptomatic carriers".

Should more of us wear face masks to help slow the spread of coronavirus?

This question is to be assessed by a panel of advisers to the World Health Organisation (WHO).

The WHO advises, external that healthy people only need to wear them if they are caring for others suspected of being infected or if they themselves are coughing or sneezing.

Earlier, England's deputy chief medical officer, Prof Jonathan Van-Tam told the UK's daily news conference that there is "no evidence" to support the widespread use of face marks.

Say goodbye to America’s record long streak of job creation.

The US government’s monthly employment report showed that almost ten years of jobs growth came to a halt in March, undone by a pandemic.

According to an employer survey, 701,000 Americans lost jobs in the first two weeks of March. A second household survey showed a stunning drop of 2,987,000 workers for the month.

All of this from data that only captures a fraction of the layoffs since it was compiled three weeks ago.

Yesterday we learnt that 6.6 million Americans filed for unemployment benefits last week, the highest in US history, on top of the prior week’s record breaking 3.3 million.

Suddenly, the Congressional Budget Office’s prediction that America could have a 9% unemployment rate at the end of 2021 looks less far fetched.

Governments around the world are advising people to socially distance themselves in order to reduce pressures on health services and stop the spread of coronavirus (Covid-19).

But what exactly is the advice on social distancing - and who should be doing it the most? And how exactly does it stop the spread of coronavirus?

The largest province in Canada has finally released its "dire" predictions on the impact of coronavirus.

Ontario, which has a population of about 15m, or about 42% of the Canada's population, says between 3,000 and 15,000 people could die by the end of the pandemic if stricter measures are not enacted.

Provincial health experts estimated 1,600 would die by the end of April.

By comparison, about 1,300 people die each year from the common flu.

The province has already closed all schools, restaurants, bars and non-essential businesses and services. Gatherings over five are prohibited.

If these measures had not been enacted, Covid-19 could have killed as many 100,000 through the course of the disease, it was estimated.

Prime Minister Justin Trudeau has promised to release the federal government's modelling soon.

There are about 3,255 cases and 67 deaths in Ontario, and 11,747 cases and 152 deaths across the country, according to the federal government's data. , external

New York Governor Andrew Cuomo told his news conference the state was still lacking in protective gear and ventilators. He said the state has around six days left of equipment at the current use rate.

"We don't have enough, period."

He announced on Friday he would sign an executive order that allows the state to take ventilators and other equipment from any institutions and redeploy them to parts of the state that need them.

Institutions will either get their ventilator back or will be reimbursed. The national guard will be deployed to collect and distribute the equipment.

"I'm not going to be in a position where people are dying and we have several hundred ventilators somewhere else," he said.

Other developments:

• Cuomo again called for a national strategy to combat Covid-19, saying states should help each other as the crisis "rolls across the country"
• He said when New York is out of the woods, they will bring their equipment and personnel "to any community that needs help"
• Cuomo said he would speak to the defence secretary about the USNS Comfort hospital ship, which has been criticised for only taking 20 patients from New York City hospitals thus far
• Cuomo said the navy's position is that disinfecting the ship from Covid-19 would be too difficult

British heavyweight Anthony Joshua’s defence of his IBF, WBA, WBO and IBO world titles against Bulgaria's Kubrat Pulev has been postponed because of the coronavirus outbreak.

The fight was scheduled to take place at Tottenham Hotspur Stadium on Saturday, 20 June.

A statement from Joshua’s promoter Matchroom Boxing said a new date for the fight "was being worked on".

Promoter Eddie Hearn said recently that if the delays go on beyond the summer and Joshua can only fight once this year, then the preferred opponent would be Tyson Fury for an all-British heavyweight unification bout.

Fury, however, is expected to complete his trilogy with Deontay Wilder and would need the latter to step aside if any fight with Joshua is to happen.
