Twenty-one patients at Gandhi Hospital in Hydrabad, India, died after power outages, according to an article on the India Times website.
Doctors said electricity first tripped around 3 p.m. and then continued to do so at regular intervals.
Although there were four generators on standby, the hospital claimed they had developed snags and could not be used after power lines were later cut off, to find the cause of the tripping.
The deaths occurred in specialty wards, including the surgical intensive care unit, neo-natal intensive care unit, respiratory intensive care unit, acute medical care unit and the emergency ward, all of which were affected by the power failure.
