Iranian President Ebrahim Raisi on Tuesday vowed to avenge the killing of the country’s top general, Qassem Soleimani, on the third anniversary of his death, The Associated Press reports.

Soleimani, head of the Quds Force of the Iranian Revolutionary Guard, was killed in a US drone strike ordered by then-US President Donald Trump in neighboring Iraq in January of 2020. He is hailed as a national icon among supporters of Iran’s theocracy, while the protesters have torn down billboards and defaced other images of him.
