Two Indonesian Christians were publicly flogged in Banda Aceh province on Tuesday for playing a children's entertainment game.
The game is seen by authorities in the conservative Muslim province as 'gambling' and therefore it violates Islamic Sharia law.
Some 300 people jeered and held up their mobile phones to record when Dahlan Silitonga, 61, and Tjia Nyuk Hwa, 45, were flogged six and seven times respectively.
The pair had been arrested along with a third man for playing a game at a children's entertainment complex that lets users exchange coins for prizes or vouchers, including cash.
They were among five people - including a couple whipped two dozen times each for showing affection in public - receiving between six and 24 lashes with a rattan stick.
Banda Aceh is the only province Indonesia that imposes sharia law and people can be flogged for a range of offences; from gambling, to drinking alcohol to having gay sex or relations outside of marriage.
Hundreds of spectators, including some two dozen tourists from neighbouring Malaysia, jeered as they group were whipped on a makeshift stage outside a mosque.
'You are old, show remorse,' the crowd screamed.
Non-Muslim Tjia Nyuk Hwa tried to hide her face in a specially provided white cloak with head-covering hijab.
'This is to create a deterrent effect, in order for people not to repeat violations of Islamic sharia law,' Banda Aceh's mayor Aminullah Usman said.
'We purposely do it in front of the public... so it won't happen again.'
The two Christians are among just a handful of non-Muslims to be punished under Aceh's strict religious law since it was adopted in 2001 as part of a deal with the central government to end a long-running insurgency.
In January, an Indonesian Christian was flogged for selling alcohol in the province at the tip of Sumatra island, which made headlines recently after local police publicly humiliated a group of transgender women.
About 98 per cent of Aceh's five million residents are Muslims subject to religious law.
Non-Muslims who have committed an offence that violates both national and religious laws can choose to be prosecuted under either system.
Christians and other non-Muslims sometimes choose a flogging to avoid a lengthy court process and jail term.
Sharia law in Banda Aceh: Public lashings in Indonesia
Aceh is the only province in Indonesia, the world's most populous Muslim-majority country, which implements Islamic law, or Sharia.
Last year, two gay men who admitted having sex were flogged in Aceh, with each receiving 100 strokes of the cane, drawing heavy criticism from rights groups.
Gay sex is not illegal in the rest of Indonesia, which mainly follows a criminal code inherited from former colonial ruler the Netherlands.
The province of Banda Aceh began implementing Sharia law after being granted autonomy in 2001 – an attempt by the government in Jakarta to quell a long-running separatist insurgency.
Islamic laws have been strengthened since Aceh struck a peace deal with Jakarta in 2005.
People are flogged for a range of offences including gambling, drinking alcohol, gay sex or any sexual relationship outside marriage.
More than 90 per cent of the 255million people who live in Indonesia describe themselves as Muslim, but the vast majority practice a moderate form of the faith.
The brutal and public beatings have become more prevalent this year with a number of reported incidents of those being punished collapsing in pain on stage.
Back in September 2014, Aceh approved an anti-homosexuality law that can punish anyone caught having gay sex with 100 lashes.
After a three-decade-old separatist movement, a peace agreement signed in 2005 granted special autonomy to Aceh, at the northern tip of Sumatra, on condition that it remained part of the sprawling archipelago.
As part of that deal, Aceh won the right to be the only Indonesian province to use Islamic sharia law as its legal code.
Anybody caught engaging in consensual gay sex is punished with 100 lashes, 100 months in jail or a fine of 1,000 grams of gold.
The law also set out punishment for sex crimes, unmarried people engaging in displays of affection, people caught found guilty of adultery and underage sex.
Religious police in Aceh have been known to target Muslim women without head scarves or those wearing tight clothes, and people drinking alcohol or gambling.
Over the past decade, the central government has devolved more power to regional authorities to increase autonomy and speed up development.
Engaging in homosexual acts is not a crime under Indonesia's national criminal code but remains taboo in many conservative parts of the country with the world's largest Muslim population.
The trend appeared to be slowing down after a string of worrying incidents at the turn of the new year, but the new pictures reveal the practice still looms large in Indonesia.
Men and women have collapsed in pain due to the severity of their injuries and people can be caned for something as innocent as standing too close to a partner in public or being seen alone with someone they are not married to.
