Israel said it has inflicted heavy losses on Iranian security forces since launching strikes on Iran over the weekend, estimating that between 1,000 and 1,500 members of the Islamic Revolutionary Guard Corps and other Iranian security bodies have been killed, according to an Israeli source quoted by The Jerusalem Post.
The source described the figure as a conservative assessment, noting that higher casualty estimates are circulating. The fatalities were reported in connection with Israeli operations carried out under Operation Roaring Lion, alongside the joint American campaign Operation Epic Fury, which began Saturday.
Israeli military officials said the campaign has focused on regime-linked military, intelligence, and internal security infrastructure.
Since the start of the operations, facilities tied to the IRGC, the Basij militia, and Iranian government institutions have been struck, the military said.
On Monday, Israel carried out a major round of strikes in Tehran, targeting what it described as internal security emergency bases, as well as installations used by the IRGC and the Basij.
The military confirmed that more than 10 headquarters associated with Iran’s intelligence ministry were hit during the operation, along with positions belonging to the IRGC-Quds Force.
In addition, the Israel Air Force conducted strikes against surface-to-surface missile launchers, weapons production facilities, and other sites operated by the IRGC Air Force, according to the military.
The Israel Defense Forces released infographics on March 2, 2026, outlining the locations of Iranian intelligence ministry headquarters and additional IRGC facilities targeted in Tehran. The materials were issued by the IDF Spokesperson’s Unit.
As operations continued, IDF Intelligence Directorate Chief Maj.-Gen. Shlomi Binder held an intelligence assessment on Monday with senior Intelligence Directorate officers, amid ongoing Israeli strikes and Iranian retaliatory missile launches.
“We could tactically surprise them, beginning at an unexpected hour and catching our enemies mid-gatherings. In 40 seconds, we eliminated more than 40 of the most important people in Iran…and we are not finished,” Binder told the Jerusalem Post.
“Looking at the past two years of the war, I believe we are sending a very clear message to our enemies: there is no place where we will not find them,” he added.
Israeli officials said further operations against Iranian military and intelligence targets are continuing as part of the campaign.
