Mayor Bill de Blasio said earlier this week the city was considering temporary burial of the pandemic’s dead on Hart Island, but shied away from making a firm commitment.

Troubling new images released Thursday show nearly a dozen contracted workers in protective suits burying stacks of wooden coffins in a mass grave, one week after The Post published drone footage that captured prisoners burying nearly two dozen.

Riker’s Island inmates have traditionally been given the grim duty of burying the city’s anonymous and unclaimed dead, with an average of about 25 interments per week.

But in recent days, burials have been performed by private contractors instead of prisoners — and have increased from once a week to five days a week, officials said.
