Iran's Revolutionary Guards said they attacked the "spy headquarters" of Israel in Iraq's semi-autonomous Kurdistan region, state media reported late on Monday, while the elite force said they also struck in Syria against the Islamic State.
The strikes come amid concerns about the escalation of a conflict that has spread through the Middle East since the war between Israel and Palestinian Islamist group Hamas began on Oct. 7, with Iran's allies also entering the fray from Lebanon, Syria, Iraq and Yemen.
"In response to the recent atrocities of the Zionist regime, causing the killing of commanders of the Guards and the Axis of Resistance ... one of the main Mossad espionage headquarters in Iraq's Kurdistan region was destroyed with ballistic missiles," the Guards said in a statement.
Reuters could not independently verify the report. Israeli government officials were not reachable for immediate comment.
Iran had vowed revenge for the killing of three members of the Guards in Syria last month, including a senior Guards commander, who had served as military advisers there.
Since the Oct. 7 rampage by Hamas fighters into Israeli territory and the ensuing Israeli bombing campaigns in Gaza and Lebanon, more than 130 fighters of Lebanon's Iran-backed Hezbollah have been killed in hostilities.
"We assure our nation that the Guards' offensive operations will continue until avenging the last drops of martyrs' blood," the Guards' statement said.
