In a speech marking the end of Ramadan, Iran’s Supreme Leader Ayatollah Ali Khamenei again took aim at Israel, saying the state “must” and “will” face retaliation for the bombing of the Iranian consulate in Damascus on April 1, Al Jazeera reports.

In a major escalation of Israel’s war with regional adversaries, suspected Israeli warplanes bombed Iran’s consulate in the Syrian capital on April 1 in a strike that killed seven Revolutionary Guard members, including two top generals.

“The evil regime made a mistake and must be punished and it shall be,” Khamenei said in a speech marking the beginning of Eid al-Fitr.
