"Activists, trade unions and associations gathered outside the US embassy in central Athens on Sunday to protest against recent US and Israeli strikes on Iran. Footage shows demonstrators chanting slogans and carrying Iranian flags and banners while police officers can be seen observing the rally. Greek and US flags can also be seen as crowds gathered outside the embassy compound. "We are here to condemn the US aggression. We should not get used to the images of killed babies and children, nor should we accept aggression as normal," student protester Afroditi Gkemou said. Katerina Kabosou, President of the Federation of Accountants, said dozens of workers’ unions had joined the rally to demonstrate against the "continuing imperialist intervention, including that of our country." "The latest events in Iran involving the US and Israel, but also the Greek governments that have supported these policies, have huge responsibilities," she claimed. Iranian state television had earlier confirmed that Iran's Supreme Leader Ayatollah Ali Khamenei was killed in strikes carried out on Saturday. The Supreme Leader, who had ruled since 1989, held ultimate authority over Iran's political, military and religious institutions. Iranian officials warned that Khamenei's killing would mark a turning point, with the Revolutionary Guard vowing retaliation and declaring that 'this great crime will not go unpunished.' The Israeli Defence chief stressed that the operation has not achieved its end, confirming Israeli Prime Minister Benjamin Netanyahu's announcement of another planned attack against Iran."
