The Commander of Iran's Islamic Revolutionary Guard Corps (IRGC) has vowed revenge for the killing of IRGC commander Razi Mousavi in Syria.

Mousavi was targeted in an alleged Israeli airstrike earlier this week amid the shadow war between the two countries, with his body subsequently brought to Tehran for burial.

Amidst the Gaza war, which commenced on October 7 with Hamas leading the conflict against Israel, Iran-backed militias in Syria, Iraq, Yemen, and Lebanon have also become involved.

In a televised speech, Hossein Salami declared that the retaliation for Mousavi's death would extend beyond conventional measures.

"Our revenge for the martyrdom of Sayyed Razi will be nothing less than the removal of the Zionist regime," Salami said, claiming that he had defended the Muslim nation for almost 33 years.

Mousavi played a pivotal role within the IRGC, known as the IRGC's man in Syria. Thousands of mourners gathered in Tehran's central Imam Hossein Square for Mousavi's funeral, passionately chanting anti-Israel and anti-American slogans. The crowd waved yellow flags bearing the message "I am your opponent," directly targeting Israel.

During the funeral on Thursday, Iran's Supreme Leader, Ali Khamenei, led prayers and paid tribute to Mousavi.
