The commander of Iran’s powerful Revolutionary Guard warned Friday that “our brave men will punish the Zionist regime,” escalating threats against Israel for an airstrike that killed seven of the group’s members, including two Iranian generals, earlier this week.

The strike, widely attributed to Israel, destroyed the consular section at the Iranian embassy in Syria. The attack on an Iranian diplomatic compound was a significant escalation in what has been a long-running shadow war between the two archenemies, and Israel has been bracing for an Iranian response.
