At least 174 people have died in a crush at an Indonesian football match that has become one of the world’s worst stadium disasters.

About 180 were also hurt in aftermath of home team Arema FC’s loss to bitter rivals at the overcrowded stadium late on Saturday in Malang, East Java.

The crush took place after police tear-gassed fans who invaded the pitch.

As panic spread, thousands surged towards Kanjuruhan stadium’s exits, where many suffocated.

Fifa, the world’s governing football body, states that no “crowd control gas” should be carried or used by stewards or police at matches.

One eyewitness told the BBC that police had fired numerous tear gas rounds “continuously and fast” after the situation with fans became “tense”.

“It had gotten anarchic. They started attacking officers, they damaged cars,” said Nico Afinta, police chief in East Java, adding that two police officers were among the dead.

“We would like to convey that… not all of them were anarchic. Only about 3,000 who entered the pitch,” he said.

Fleeing fans “went out to one point at the exit. Then there was a build-up, in the process of accumulation there was shortness of breath, lack of oxygen”, the officer added.
