The Israel Defense Forces (IDF) on Tuesday threatened to find and "neutralize" Iran's new Supreme Leader, Mojtaba Khamenei, and announced the assassination of Ali Larijani, Secretary of Iran's Supreme National Security Council, AFP reports.

"We don’t know about Mojtaba Khamenei, we don’t hear him, we don’t see him, but I can tell you one thing: we will track him down, find him, and neutralize him," IDF spokesman, Brigadier General Effie Defrin, told reporters.

Earlier, Iran confirmed Ali Larijani's death.
