"There were around 1000 HMI members," he told Fairfax Media. "We were sitting about 30 to 100 metres from the broken barricade, we backed away immediately after the tear gas shooting. My eyes hurt, my face was hot, we scrambled for water to wash our faces. We backed away immediately. I don't have any reports yet if any of our members were hurt. It was a peace action, we stuck to that."Mr Mulyadi said the fight had been initiated by a group next to them. "There was a small incident in the afternoon, some garbage, not tires, were burned, but it was put out immediately. It was a peace action." The rally, spearheaded by the militant Islamic Defenders Front, came about because Muslim hardliners want Jakarta governor Basuki Tjahaja Purnama, widely known as Ahok, to be jailed for allegedly insulting the Koran. About 20,000 police and military personnel secured the route of the demonstration in Central Jakarta amid fears it would be hijacked by extremists keen to foment violence.

"Arrest and try Ahok and his cronies dead or alive," read a sign suspended from Istiqlal mosque, the largest mosque in South East Asia. Police during the rally against Ahok in Jakarta.

Ahok is being investigated by police for alleged blasphemy after he appeared to suggest in an edited video transcript that voters were being deceived by a verse in the Koran.

Others say the scripture should be understood in its context – a time of war – and not interpreted literally. Muslim protesters chant slogans near burning police trucks during the clashes. Credit:AP

Ahok apologised for the offence caused by his comments and insisted he was not criticising the Koranic verse but those who used it to attack him. However many Muslims continue to call for him to be arrested and jailed. Clashes with police at a rally protesting against Ahok in Jakarta. Credit:Roni Bintang Jakarta had been on tenterhooks in the days leading up to the protest, which had ignited ugly anti-Chinese sentiment throughout the country, and sparked fears of a repeat of the 1998 riots. It is estimated more than 1000 people died in the 1998 riots which began as a protest against the Suharto regime but often targeted ethnic Chinese, looting and burning their shops.

"People will not accept it if Ahok is free. He has insulted Islam and Islam is our belief. The best thing is for the President [Joko Widodo] to instruct the police to arrest Ahok before the worst happens," Dr Ratman told Fairfax Media.

Ian Wilson, from the Asia Research Centre at Murdoch University, said it was important to consider some of the context of the protests. He said since taking office as governor in 2014, Ahok had presided over one of the most aggressive eviction campaigns in the modern history of the city.

"What many have failed to consider, or simply ignored, is the massive groundswell of anger and resentment generated by this policy regime. It has spread far beyond the tens of thousands directly impacted through extended family, friends, neighbours and social, cultural and work networks," he wrote in New Mandala. "Reliable statistics on the numbers directly affected are difficult to come by. However, reports compiled by the Jakarta Legal Aid Foundation estimate that more than 16,000 overwhelmingly poor and working class families have been displaced in the past two years alone. Only 30 per cent have been offered any alternative accommodation, the social and economic impacts of which have been devastating." "This anger has, unsurprisingly, sought to find avenues of expression and amelioration." Loading With Karuni Rompies and Amilia Rosa
