Tesla has reopened its only US electric car plant in California, despite local orders against manufacturing.

On Monday, the company's chief executive Elon Musk tweeted that production had restarted and he would be "on the line with everyone else".

US states and local governments are trying to determine the best way to open up after lockdown.

Mr Musk previously vowed to move the firm's headquarters out of California if the plant was not allowed to reopen.

He has been vocal about the lockdown orders in recent weeks.

Mr Musk recently celebrated plans to relax restrictions across the country, writing on Twitter: "FREE AMERICA NOW". He has also dismissed as "dumb" concerns about the coronavirus.
