Atleast 174 people have died in a crush at an Indonesian football match.
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”.
Fifa President Gianni Infantino said it was “a dark day for all involved in football and a tragedy beyond comprehension”.
Early reports put the death toll at about 130, but officials later announced a significant rise to 174, with 11 more people seriously injured.
President Joko Widodo has ordered that all matches in Indonesia’s top league must be stopped until an investigation has been carried out.
The Indonesian football association (PSSI) said it had launched an investigation, adding that the incident had “tarnished the face of Indonesian football”.
Violence at football matches is not new in Indonesia, and Arema FC and Persebaya Surabaya are long-time rivals.
Chief Security Minister Mahfud MD posted on Instagram that 42,000 tickets had been sold for the match at Kanjuruhan stadium, which has a stated capacity of 38,000.
President Widodo called for this to be the “last soccer tragedy in the nation” after ordering that all Liga 1 games should be paused pending an investigation.
Muhamad Dipo Maulana, 21, who was at the match, told BBC Indonesian that after the game had ended a few Arema fans went on the pitch to remonstrate with the home team players but were immediately intercepted by police and “beaten”.
“Police with dogs, shields, and soldiers came forward,” Mr Dipo told the BBC.
He said he had heard more than 20 tear gas shots towards spectators at the stadium.
“There was a lot, like bang, bang, bang! The sound was continuous and fast. The sound was really loud and directed to all the stands,” he added.
Mr Dipo said he saw people in disarray, panicking and suffocating while trying to get out of the stadium. There were many children and old people who were affected by the tear gas, the eyewitness added.
The stampede is one of the worst of a tragically long line of stadium disasters.
In 1964, a total of 320 people were killed and more than 1,000 injured during a stampede at a Peru-Argentina Olympic qualifier in Lima.
In 1985, 39 people died and 600 were hurt at the Heysel stadium in Brussels, Belgium, when fans were crushed against a wall that then collapsed during the European Cup final between Liverpool (England) and Juventus (Italy).
In the UK, a crush developed at the Hillsborough stadium in Sheffield, resulting in the deaths of 97 Liverpool fans attending the club’s FA Cup semi-final against Nottingham Forest. (BBC)
