US officials in Missouri have condemned raucous crowds who packed a pool and bar at a popular holiday venue after video footage of the weekend partying spread on social media.

The party at Lake of the Ozarks attracted furious criticism from nearby St Louis county, where many people travelled to the lake over the Memorial Day holiday despite concerns over the coronavirus pandemic.

“This reckless behaviour endangers countless people and risks setting us back substantially from the progress we have made in slowing the spread of Covid-19,” St Louis county executive Sam Page said in a statement on Monday.
