India's Election Commission Tuesday banned all electoral victory rallies in the country, a day after a higher court held the constitutional body responsible for the ferocious second wave of Covid-19 and threatened to book top poll officials for murder. The results for assembly elections in five Indian states -- West Bengal in the east, Assam in the northeast, and Tamil Nadu, Kerala and Puducherry in the south -- are due on May 2. "Not more than two persons shall be allowed to accompany the winning candidate or his/her authorised representative receive the certificate of election from the Returning Officer concerned," the Election Commission said in a notification.

"Your institution is singularly responsible for the second wave of Covid-19. Your officers should be booked on murder charges probably," the court told the Election Commission on Monday, in the wake of a plea against crowded election campaigns in Tamil Nadu. "You have failed to enforce Covid safety rules like masks, sanitisers and distancing during campaigning despite court orders. Were you on another planet when the election rallies were held," a two-judge bench, led by Chief Justice Sanjib Banerjee, had said. The court had also threatened to halt the counting of votes on May 2 "if a blueprint is not in place by then". The court's rebuke came on a day when India recorded a whopping 3.52 lakh new Covid-19 cases in 24 hours amid an acute shortage of oxygen in hospitals across the country. In fact, the oxygen crisis in India, particularly in the national capital, is worsening with each passing day. Hospitals after hospitals in Delhi are sending out SOS messages to health authorities daily, seeking adequate supply of the life-saving gas. Last week, at least 50 Covid patients on life support died at two leading Delhi hospitals due to oxygen shortage.

"We had been allotted 3.5 metric tonnes of oxygen from the government. The supply was to reach us by 5 in the evening, but it reached around midnight. By then, 25 patients had died," Dr DK Baluja, the hospital's Medical Director had said. On Friday morning too, another leading hospital in Delhi announced the deaths of 25 patients in 24 hours due to a shortage of oxygen. In a statement, Sir Ganga Ram Hospital had said, "25 sickest patients have died in last 24 hours. Oxygen will last another two hours. Major crisis likely. Lives of another 60 sickest patients at risk, need urgent intervention." It may also be mentioned here that 24 Covid patients on ventilator at a government hospital in the western Indian state of Maharashtra died on Wednesday after their oxygen supply ran out following leakage of the life-supporting gas from a tanker. The tanker was brought to Zakir Hussain Municipal Hospital in the state's Nashik district to replenish the oxygen cylinders at the medical facility for continuous supply to the 150-plus Covid-19 patients on life support. The US, the world's worst-hit country, has, meanwhile, assured India of all assistance, in its hour of crisis. "Just as India sent assistance to the United States as our hospitals were strained early in the pandemic, we are determined to help India in its time of need," US President Joe Biden said in a tweet Sunday.
