"Violent clashes erupted on Sunday evening at the entrance to Baghdad’s Green Zone as security forces faced off with crowds demonstrating against the assassination of Iran’s Supreme Leader, Ali Khamenei, during a joint US-Israeli operation. Footage shows parts of the confrontations, with protesters gathering and throwing objects near the heavily fortified area in central Baghdad, where the U.S. Embassy is located. The videos also capture security forces firing tear gas and stun grenades at the demonstrators - and some seen washing their faces after the assault. The clashes continued from sunset until midnight. The area had already witnessed confrontations between the two sides earlier in the day. Iraq declared three days of national mourning following the announcement of Khamenei’s assassination. Government spokesperson Bassem Al-Awadi said that “Iraq, its government and people, affirms its solidarity with the Islamic Republic of Iran during these difficult circumstances.” On Saturday, the United States and Israel launched a joint attack on Iran. In response, Iran’s Revolutionary Guard announced the launch of “large-scale missile and drone attacks” on Israel, and reports said U.S. bases in the United Arab Emirates, Bahrain, Qatar, Iraq and Kuwait were targeted. Trump later confirmed Khamenei’s death in the strikes, describing it as “the greatest opportunity for the Iranian people to reclaim their country.” Iran’s Revolutionary Guard said in response to Khamenei’s assassination: “This grave crime will not go unpunished, and a new chapter will be written in the history of the Islamic world.” Khamenei was the Supreme Leader of the Islamic Republic of Iran and the country’s highest political and religious authority. He assumed the position on June 4, 1989, following the death of the founder of the Islamic Republic, Ruhollah Khomeini. "
