The tragic incident has taken place in the province's Gorakhpur constituency, triggering a chaos.

At least 30 children have died in the last two days alone, forcing the provincial government to order an investigation.

However the government has dismissed all claims that the deaths are somehow related to the short supply of oxygen.

Contrary to the state government's claim, data shows otherwise.

At least 23 children died in the state-run Baba Raghav Das Medical College on Aug 10, the very day that the firm which used to provide oxygen to the facility stopped doing so owing to a payment dispute.

"There have been no deaths due to lack of oxygen supply," the local media quoted state Medical Education Minister Ashutosh Tondon as saying.

He added that an investigation has been ordered by the District Magistrate and the report will be out within the next 24 hours.

"Those responsible will not be spared," said state Health Minister Siddharth Nath Singh. "Chief Minister visited the BMD hospital on August 9, doctors there did not make him aware about oxygen shortage."

An inquiry has also been ordered by UP Chief Minister Yogi Adityanath on Saturday morning.

It is notable that that Yogi Adityanath is also the elected Member of Parliament from Gorakhpur.

Meanwhile, decoding the deaths, a lawmaker from the incumbent Bharatiya Janata Party, Kamlesh Pashwan, who visit the facility, said, "An average 8-10 patients die every day in this hospital, which gets a large number of encephalitis patients."

Following the incident, the BJP-ruled state government has come under fire from the opposition.

"Families of the dead were sent off with the bodies, they did not even do autopsies... extremely unfortunate," Former UP Chief Minister Akhilesh Yadav tweeted.

Opposition leader and Congress supremo Sonia Gandhi too condemned the incident.

Gandhi was quoted in the media as saying, "I am pained beyond words by the tragic deaths of 30 children in Gorakhpur. My heart goes out to their families."

Another opposition top brass Lalu Prasad Yadav, who heads the Bihar-based Rashtriya Janata Dal outfit, took shots at UP Chief Minister Yogi Adityanath.

Questioning the UP Chief Minister's competence, Yadav tweeted, "Pained to hear abt loss of innocent lives in #Gorakhpur hospital. Total incompetence & negligence of Yogi govt. Culprits must be punished."
