TEHRAN — Iran’s highest Revolutionary Guards commander issued a threat against Israel after the death of an Iranian general in an Israeli helicopter strike along the border with Syria, saying that “destructive thunderbolts” awaited.

The commander, Mohammad Ali Jafari, said in a statement distributed by the state news media on Tuesday that the fact that an Iranian general had been so close to Israeli territory proved that Iran’s power “has passed over geographical borders.”

The Iranian general, Mohammad Ali Allahdadi, was killed along with a Hezbollah commander and the son of the group’s former military leader, Imad Mughniyeh, in Sunday’s attack on a Hezbollah convoy near the Israeli-occupied Golan Heights.

After issuing a ritual denunciation of the “Zionist regime,” Mr. Jafari said: “These martyrdoms prove that we should not distance ourselves from the jihad; the Zionists should prepare themselves for our shattering thunderbolt. They have experienced our rage in the past.”
