Khamenei mocked US officials as "American clowns" and criticized France, Germany and the UK as "lackeys" of the US that can't be trusted. He also expressed his condolences to the families of victims of the plane crash.It is rare for Khamenei — the highest spiritual and political authority in Iran — to lead Friday prayers, and the move is thought to be an effort to rally support after several tumultuous weeks that have piled pressure on the Islamic Republic's rulers. Iran's most important general, Qasem Soleimani, was killed in a US drone strike in Iraq two weeks ago, and Iran retaliated with strikes on US targets, bringing Tehran and Washington briefly to the brink of all-out conflict. Iran's military then shot down a Ukrainian commercial flight in Tehran, killing all 176 people onboard, including 82 Iranians, prompting days of protests and finger-pointing between rival factions of the government.In a defiant sermon Friday, Khamenei described the "martyrdom" of Soleimani and Tehran's retaliation against the US as "acts of God, not man," and boasted that Iran had delivered a slap in the face to the United States."What took place could not have been the work of any human actor, only the hand of God," Khamenei said. "The day in which the missiles of [Iran's Revolutionary Guards] rained down upon the American base, that was also the day of the Almighty.""We saw history in the making. These are not normal days. The fact that a power, a nation, does possess the spiritual strengths in order to respond to the biggest bullying power in the world with such a slap in the face, this shows the divine hand, the hand of God", the Supreme Leader said.Khamenei also railed against US President Donald Trump and Secretary of State Mike Pompeo, who have said on social media that they stand with Iranian protesters.He said "American clowns" lie to the public when they say the US is with the people of Iran. "If you stand in close proximity to Iran, it is with the intention of driving a knife into the chest of the people," he said. Huge crowds were present to witness the rare sermon, with President Hassan Rouhani in the front row alongside parliament speaker Ali Larijani. The last time Khamenei presided over Friday prayers was in 2012 to mark the 33rd anniversary of the Islamic Revolution. He also led prayers in 2009 amid protests that erupted after disputed presidential elections.Over the past few days Iranian radio broadcasts and television had been encouraging people to join the prayers.They come at a pivotal time for Iran, after vigils to mourn those who died in the Ukraine International Airlines crash quickly turned into mass anti-government demonstrations, with calls for Khamenei to step down and for those responsible for downing the plane to be prosecuted.Iran's military initially denied shooting down the plane before admitting to it several days later, saying the plane was "accidentally hit by human eRead More – Source
