Iran's Supreme Leader Mojtaba Khamenei extended condolences for a senior general of the Islamic Revolution Guard Corps (IRGC), saying that "assassinations and crimes" against Iranian leadership will not halt the country's course.

In a written statement, Khamenei praised Majid Khademi, head of the IRGC's Intelligence Protection Organization, for decades of "silent efforts in the security, intelligence, and defense fields" of Iran.

He also accused Israel and the United States of turning to "terrorism and assassination" after "successive defeats." Khademi was killed in Tehran on Monday in an airstrike claimed by Israel.

Khamenei extended condolences to Khademi's family and comrades, as well as the other commanders of the IRGC's Intelligence Organization.

Khademi was appointed as the head of the intelligence organization in June last year following the 12-day war between Iran and Israel, in which Mohammad Kazemi, the organization's former chief, had been killed.

Before his appointment, Khademi served as the head of the IRGC's Intelligence Protection Organization.

On Feb. 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Iran's Supreme Leader Ali Khamenei, along with senior military commanders and civilians. Iran responded by launching waves of missile and drone strikes targeting Israel and U.S. bases and assets in the Middle East.
