The Syrian state media and Sky News Arabia reported Syria's air-defense system also intercepted two Israeli surface-to-surface missiles.
Syria's state news agency SANA said the surface-to-surface missiles, which were fired shortly after midnight on December 1, caused material damage. There has been no official Israeli comment on the attack, however, the message is clear, that Iranian bases will not be tolerated, as senior officials in Israel have stated. However, reports from Lebanon's Al-Mustaqbal TV and the Saudi-owned Al-Arabiya network stated that information on the deaths emerged from accounts on the Telegram messaging application linked to Iran's Revolutionary Guard Corps. The incident reportedly occurred Friday night, with IDF planes attacking the Iranian base at al-Kiswah, south of Damascus.
The Israeli military has not confirmed that it carried out the strike. Israel has long justified its attacks inside Syria by claiming to be acting against Hezbollah and Iranian facilities and arms depots.
