US President Donald Trump has ordered General Motors to make ventilators for coronavirus patients after attacking the car giant's chief executive.

He invoked the Korean War-era Defense Production Act, which allows a president to force companies to make products for national defence.

Mr Trump said that "GM was wasting time" and action was needed to save American lives.

The US now has 104,256 cases of the virus, the most in the world, reports BBC.

With over 1,700 fatalities, America's Covid-19 death toll still lags far behind Italy and China.
