Indonesian authorities said on Sunday that at least 129 people, including two police officers, died after violence broke out following a football match in the East Java province.

East Java police chief Nico Afinta said 34 people died in the stadium, and the rest died either on their way to the hospital or at the hospital where they were being treated.

In total, more than 300 people were taken to nearby hospitals for treatment after the unrest that police characterized as "riots."

Afinta said he expected the number of deaths to rise since the condition of some people being treated at hospitals was deteriorating.

Fans angered after host team's loss

Clashes broke out after angry fans stormed onto the football field after the host team, Arema FC, was defeated.

Arema FC lost 3-2 to Persebaya Surabaya, the first loss in more than two decades to their bitter rival.

Both are teams from the East Java province, and the game took place at the Kanjuruhan stadium in the Malang district.

Afinta said police retaliated by firing rounds of tear gas into the stands after two police officers were killed.

People panicked and hundreds tried to run out of an exit gate at that time, leading to chaos.

Some people suffocated and 34 were trampled to death at the stadium, Afinta said.

The Football Association of Indonesia (PFFI) said it was suspending the football league for a week and launching an investigation into the incident.

Arema FC was also banned from hosting home games for the rest of the season, the PFFI said.

Indonesia mulls spectators ban

Indonesia's Sports Minister Zainudin Amali told reporters he was sorry about the incident and that authorities would re-evaluate safety at football matches.

"This is a regrettable incident that 'injures' our football at a time when supporters can watch football matches from the stadium," Amali said.

"We will thoroughly evaluate the organization of the match and the attendance of supporters. Will we return to banning supporters from attending the matches? That is what we will discuss," Amali added.

Afinta, the police chief, said authorities had recommended that the match be attended by Arema FC fans only, given the fierce rivalry between the clubs.

"We regret and deplore the tragedy," Afinta told reporters.
