Corruption and criminal negligence, says Oppn as ruling BJP hits back

Targeting the government, Congress president Mallikarjun Kharge posted on X, "Corruption and criminal negligence is responsible for the collapse of shoddy infrastructure falling like a deck of cards, in the past 10 years of Modi Govt."

"On March 10th, when Modi ji inaugurated the Delhi Ariport T1, he called himself 'Doosri mitti ka insaan...' All this false bravado and rhetoric was only reserved for quickly indulging in ribbon-cutting ceremonies before Elections! Our heartfelt condolences to the victims of the Delhi airport tragedy. They bore the brunt of a Corrupt, Inept and Selfish Govt," he added.

Trinamool Congress MP Saket Gokhale wrote on X,"SHOCKING & tragic news this morning. The roof at Delhi Airport’s has T1 collapsed this morning and, until now, 3 people are reported dead. For election campaigning, Modi had hurriedly “inaugurated” T1 in March even while it was under construction.

"Why shouldn't PM Modi be charged with culpable homicide? He’s directly responsible for the death of 3 people who lost their lives because Modi was desperate to campaign."

Countering the Opposition, Civil Aviation Minister Ram Mohan Naidu Kinjarapu, said: "I want to clarify that the building inaugurated by PM Narendra Modi is on the other side and the building that collapsed here is an old one which opened in 2009."

He announced a compensation of INR 20 lakh for the dead and INR 3 lakh for the injured.
