Israel’s massive airstrike attack left Iran’s military leadership in crisis as it killed several senior Iranian commanders — including the head of its Revolutionary Guard.

Iranian Major Gen. Hossein Salami, commander of Iran’s Islamic Revolutionary Guard Corps, was killed in Israel’s attack on the Islamic Republic, according to people familiar with the matter and Iranian media.

Tel Aviv has launched hundreds of airstrikes over the past two days and killed several key leaders in the theocratic nation.
