An Israeli missile strike on Syria's capital Damascus on Saturday killed four members of Iran's Revolutionary Guards.
Iranian state television said the targeted building was the residence of Iranian advisers in the Syrian capital.
Syrian state media reported an Israeli "aerial attack" on a building in the Mazzeh neighborhood of Damascus and said Syrian air defenses had shot down a number of missiles.
Nour News, which is believed to be close to Iran’s intelligence apparatus, identified two of the dead in Damascus as Gen. Sadegh Omidzadeh, the intelligence deputy of the guard's expeditionary Quds Force in Syria, and his deputy, who goes by the nom de guerre Hajj Gholam. The guard later issued a statement identifying the dead as Hojjatollah Omidvar, Ali Aghazadeh, Hossein Mohammadi and Saeed Karimi. It gave no ranks for them. The difference in information could not be immediately reconciled.
An opposition war monitor, the Syrian Observatory for Human Rights, said at least six people — five Iranians and a Syrian — were killed in the missile attack that struck while officials from Iran-backed groups were holding a meeting. The Observatory's chief, Rami Abdurrahman, said three of the Iranians were commanders, adding that four other people are still missing under the rubble.
