If you check the very end of the current version of the article at https://nypost.com/2021/04/26/covid-19-surge-swallowing-people-in-india-like-a-monster/ you will see "Editor’s note: An earlier version of this story included an Eyepress video provided by Reuters, which incorrectly identified gas leak victims as COVID-19 victims."

Snapshots of older versions without the editor's note can be found at https://web.archive.org/web/20210426150716/https://nypost.com/2021/04/26/covid-19-surge-swallowing-people-in-india-like-a-monster/ and https://archive.is/hxmt4 but the image is not in them.
