Arema FC supporters at the Kanjuruhan stadium in the eastern city of Malang stormed the pitch late on Saturday after their team lost 3-2 to Persebaya Surabaya, the first loss in more than two decades to their bitter rival.

Police, who characterised the unrest as "riots", tried to persuade fans to return to the stands and fired tear gas after two officers were killed. 

Many of the victims were trampled to death, according to police.

East Java police chief Nico Afinta said many people were crushed and suffocated when they ran to one exit. 

He initially said a total of 127 people had died, but the toll was later raised to 129. 

A hospital director told local TV that one of the victims was five years old. 

Images captured from inside the stadium during the stampede showed huge amounts of tear gas and people clambering over fences.
