Iran vows retaliation for Israeli airstrike killing military adviser in Syria.

Iran has accused Israel of carrying out a "criminal strike" in Syria that killed an Iranian military adviser, Milad Heidari, who was a member of the paramilitary Revolutionary Guard. Israel has carried out hundreds of strikes on targets inside government-controlled parts of Syria in recent years, including attacks on the Damascus and Aleppo airports, but has rarely acknowledged specific operations. The strikes targeted an arms depot for government forces and Iran-backed groups just south of Damascus. The Revolutionary Guard has warned that Israel will receive an answer for the crime.
