Ambulance workers in Los Angeles, California, received orders not to carry patients whose survival chance is low.
This ordered was given as officials say that the region might hit up 1,000 deaths per day related to COVID-19 and hospitals are overwhelmed with patients.
Emergency workers are also advised to ration oxygen which is in limited supply due to the pandemic.
Officials fear a post-holiday spike as hospital beds are running low.

The number of patients in California due to coronavirus has doubled in the past month. Every six seconds, a new infection is recorded, and the condition of LA is significantly worse.
The slower-than-expected US vaccine rollout also comes as criticism mounts. On Monday, The Centers for Disease Control and Prevention (CDC) said that only over 4.5 million patients had been given their first jab of the 15.4 million vaccine doses that have been provided so far.
