Smuggled video from inside an infamous Iranian prison captured the moment six dissidents broke into song to defy the Islamic regime one last time before they were hanged.

The six men, all executed for their alleged actions against the regime, were seen standing in a courtyard at the notorious Ghezel Hesar prison as they made their final stand with a song of resistance, The Sunday Times reported.

“Your rival stands before you now, hardened in the flame — I am the faith, I am revolt, with belief I take my stand — I’ve sworn an oath upon my blood, the tyrant’s throne shall shatter,” the men calmly sung.

The video was reportedly filmed in the last week of February, with the men identified as Vahid Baniamerian, Babak Alipour, Abolhassan Montazer, Pouya Ghobadi, Akbar Daneshvarkar and Mohammad Taghavi.

Ghobadi, 33, was confirmed to be executed on March 31 after he was allegedly tortured by the regime, which accused him of armed rebellion against the state, according to Amnesty International.

Baniamerian, 33, who was accused of the same crime, was featured in another smuggled video in a direct address to then Iranian Supreme Leader Ayatollah Ali Khamenei.

“To the Supreme Leader who wants to execute us to create fear in society. I want to remind you that I and those like me rose from the blood of freedom-loving youth,” he said before being executed on April 4.
