Iran, always keen to score points against its longtime foe the United States, took Washington to task on Saturday over the killing of a black man in by a white police officer that has sparked angry protests over racial injustice.
U.S. Secretary of State Mike Pompeo hit back saying, "You hang homosexuals, stone women and exterminate Jews."
"Some don't think #BlackLivesMatter," Iranian Foreign Minister Mohammad Javad Zarif wrote on Twitter. "To those of us who do: it is long overdue for the entire world to wage war against racism. Time for a #WorldAgainstRacism."
"The U.S. government is squandering its citizens' resources, whether its adventurism in Asia, Africa, or Latin America...," Zarif said in a tweet partly based on a message that Pompeo sent to Iranian street protesters in 2018, but with some of the words changed.
Iran's Foreign Ministry earlier denounced the police killing of the unarmed black man in Minneapolis,George Floyd, which has sparked protests in several cities, some which have turned violent.
A ministry statement condemned what it called "the tragic murder of black people and deadly racial discrimination in the United States".
"The voices of the protesters must be heard ... (and) the repression of suffering Americans must be stopped immediately," the ministry statement said.
