New Delhi/Bengaluru/IBNS: Prime Minister Narendra Modi on Friday expressed grief over the deaths of 11 people in a stampede incident in Bengaluru during IPL victory celebrations of Royal Challengers Bengaluru (RCB) that left 11 people dead and called the tragedy "heartrending".

"The mishap in Bengaluru is absolutely heartrending. In this tragic hour, my thoughts are with all those who have lost their loved ones. I pray that those who are injured have a speedy recovery: PM @narendramodi," the Prime Minister's office posted on X.

At least 11 people died and 50 others injured as a stampede broke out outside Bengaluru's Chinnaswamy Stadium where a massive crowd gathered to celebrate Royal Challengers Bengaluru's victory in the Indian Premier League (IPL), media reports said.

The fatal stampede broke out as the crowd swelled and turned uncontrollable outside the stadium, which has a capacity of roughly 40,000 people.

The BJP has accused the Congress-led government in the state of seeking publicity and not making adequate arrangements for the celebration.

"It's heartbreaking to see such loss because of poor planning and crowd mismanagement. The state government in Karnataka has clearly failed in its responsibility. Celebrations are one thing, but the State government without proper planning, without taking emergency services into confidence, took this urgent and unfortunate decision. This could have been avoided (sic)," senior BJP leader and Union Minister Pralhad Joshi wrote on X.

"The government is responsible for this and accountability needs to be fixed," he added.

Slamming the Congress-led state government, Bharatiya Janata Party (BJP) IT Cell head Amit Malviya wrote on X, "This heartbreaking incident could have been avoided. The lack of basic administrative foresight and failure in crowd control by the state government has led to an irreparable loss. Accountability must be fixed. Lives were lost due to negligence, not chance."

Meanwhile, Chief Minister Siddaramaiah, during a press conference this evening, stated that the administration did not expect the tragedy, as the stadium can accommodate 35,000 people.

"But the number of people who turned up is estimated to be two-three lakhs. We assumed there would be as many people as the stadium would accommodate or a bit more, but not as many as had actually turned up," Siddaramaiah said.

He announced a compensation of Rs 10 lakh to the families of those who were killed in the stampede, and free treatment for the injured.

"I have ordered a magisterial inquiry into this tragedy. Appropriate action will be taken against the guilty. Instructions have been given to submit the investigation report within 15 days," he said.
