BENGALURU, India (AP) — At least 11 people are dead and more than 30 injured after a stampede on Wednesday as crowds tried to enter a cricket stadium in southern India’s Karnataka state, authorities said.

The crush happened as tens of thousands of cricket fans gathered outside the M. Chinnaswamy Stadium in Bengaluru city to celebrate the winners of the Indian Premier League, the world’s most popular T20 cricket tournament.

Karnataka state’s Chief Minister Siddaramaiah, who only uses one name, said the crowd tried to break one of the stadium’s gates and enter to take part in celebrations.

Eleven people were killed and 33 others were injured, Siddaramaiah said, adding that most of the injured were stable and receiving treatment in hospitals.

“At a time of celebration, this unfortunate event should not have happened. We are saddened by this,” he told reporters.

"No one expected this crowd,” he said.

Cricket fans had come out to celebrate Royal Challengers Bengaluru’s first Indian Premier League title win on Tuesday. The team had given away free passes to fans for the event through its website, and urged them to follow guidelines set by police and authorities.

Local TV news channels showed some people stretched out on the ground and emergency personnel carrying people into ambulances, while celebrations inside the stadium continued.

D.K. Shivakumar, the deputy chief minister of Karnataka state, told reporters that “the crowd was very uncontrollable."

The Board of Control for Cricket in India, which organizes the IPL, in a statement called the incident “unfortunate.”

“This is a negative side of popularity. People are crazy for their cricketers. The organizers should have planned it better,” BCCI secretary Devajit Saikia said.

Stampedes are relatively common in India when large crowds gather. In January, at least 30 people were killed as tens of thousands of Hindus rushed to bathe in a sacred river during the Maha Kumbh festival, the world’s largest religious gathering.
