As the November presidential election approaches, US President Donald Trump has held his first indoor campaign rally in three months.

But the event angered local officials, who said the size of the crowd violated state rules banning gatherings of more than 50 people.

Participants at the rally in Henderson, Nevada, were seated close together and most did not appear to be wearing face masks. A number of media outlets, including CNN, did not send their crews for safety reasons.

The president's last major indoor rally in Tulsa, Oklahoma, in June caused controversy, with a number of staffers testing positive for coronavirus just hours before the event began.

The US has confirmed almost 200,000 Covid-19 deaths since the pandemic began, the highest figure in the world.
