Conservative actor James Woods took a swipe at actress Alyssa Milano, telling her to 'buy more ammo' after she urged Americans to stop stockpiling guns during the COVID-19 pandemic. 

On Thursday, Milano, 47,  shared a video to Twitter to encourage her followers to practice gun safety after reports revealed nervous citizens have caused a surge in gun and ammunition sales.

'Americans bought over 2 million firearms in March of 2020, over a million more than this time last year. We have to keep each other safe by social distancing and washing our hands and not bringing dangerous firearms into our homes,' she wrote.

'I know we that we are all scared and really stressed out during these uncertain times. But that's exactly why stockpiling weapons could have dire consequences for our personal safety and those around us. '

Milano added that guns being purchased during the outbreak - which has infected 469,450 and killed 16,715 in the US - could 'end up being used in households, schools, churches, bars and on our streets in the future.'
