IRNA � Iranian Foreign Minister Mohammad Javad Zarif in a message referred to US� recent crime of killing a black American, saying its maximum pressure couldn�t bring Iranians to their knees.

�The �knee-on-neck� technique is nothing new: Same cabal�who've admitted to habitually �lie, cheat, steal"�have been employing it on 80M Iranians for 2 yrs, calling it �maximum pressure,� Zarif wrote on his Twitter account.

�It hasn't brought us to our knees. Nor will it abase African-Americans,� it added.

In recent days, American people poured into streets to protest against the death of George Floyd - a black man who was unarmed and died in hands of the police putting pressure on his throat until he choked.

Meanwhile, in a separate message earlier, Iranian Foreign Ministry had said, �Iran regrets the tragic murder of black Americans, denounces deadly racial profiling in the United States & urges the authorities to do justice for every case."

"The protestors' voice must be heard. In doing so, suppressing the suffering of Americans & #PressFreedom must URGENTLY be stopped," it added.

In another development earlier, Iranian Foreign Ministry Spokesman Abbas Mousavi in a message referred to the brutal killing of a black man by the US police and said the US Administration even glorifies systematic racism and white supremacism.
