US President Donald Trump again lashed out at China over the coronavirus pandemic, blaming Beijing for “mass worldwide killing", according to AFP.

His tweet, which also referred to an unidentified “wacko in China,” was the latest heated rhetoric from the White House, where Trump is making attacks on Beijing a centerpiece of his November re-election bid.

“It was the 'incompetence of China', and nothing else, that did this mass worldwide killing,” the president tweeted.
