JERUSALEM - At least two babies have been found dead and 53 more were left severely ill at the unlicensed facility in Jerusalem.
Babies were found in closets, strollers, and even near toilets, in dangerously high heat.
Authorities are planning autopsies to determine the exact cause of death.
But even that has sparked outrage.
Hundreds are protesting planned post-mortems, which clash with Ultra-Orthodox Law.
Three caregivers have been arrested as investigators probe if the deaths are linked to a faulty heating system.
Authorities say overcrowding and severe neglect may have also contributed.
