Twenty-three children died between Wednesday and Thursday.
The state government in India's Uttar Pradesh has ordered an investigation into the mass deaths of children at a hospital over a possible medical negligence. According to the numbers, as provided by the officials, 17 children have been reported to have died in the neo-natal ward, five in the Acute Encephalitis Syndrome (AES) ward and 8 deaths in the general ward.
The parents said the company that supplies oxygen to the hospital had earlier threatened to stop oxygen distribution unless the government paid their long overdue bills.
Spending on public health in India, relative to the country's GDP, is among the lowest in the world.
As per the locals, though the hospital is supposed to provide free medical assistance, neither there is proper medical facility available nor are the patients provided free medicines.
Siddharth Nath Singh, the health minister of UP, said: "The death of children is very unfortunate and the government will set up an inquiry committee to ascertain if any lapse has occurred".
The ruling Bhartiya Janta Party (BJP) is also governing the northern Indian state of Uttar Pradesh.
On August 9, a day before the oxygen supply was disrupted, Adityanath had visited the hospital.
"Everybody said shortage of liquid oxygen led to the tragedy", Azad said.
"The reasons for the disruption of oxygen supply are being investigated but our probe has revealed that no deaths happened because of it", Singh told reporters after a visit to the hospital.
District magistrate Rajeev Rautela said in press conference, "We have been told that BRD witnessed disturbance in liquid oxygen supply since last night as firm withdrew supply owing to non-payment", he said.
"Even as 90 jumbo oxygen cylinders were pressed into service to maintain the supply on Friday, the hospital ran out of oxygen around 1.00am", it said. Of these, 129 children had died, said Satish Chandra, a hospital spokesman.
Meanwhile, leaders of Opposition parties have reacted sharply to the development.
While Dr Misra, who has been suspended now, took responsibility for the death of the children, he contradicted the Yogi Adityanath government's statement.
