The diplomatic mission said in a post published on X on Wednesday that the "assassination and targeted killing" of Mousavi by the Israeli regime airstrike "was not only an outrageous violation of international law and the UN Charter, but also of universal human rights law.”
General Mousavi was martyred by the Israeli regime on Monday in the residential neighborhood of Zeinabiyah district in the suburbs of Damascus on Monday, while on an advisory mission in Syria.
He was one of the companions of Iran's top anti-terror commander, Lieutenant General Qassem Soleimani, who was assassinated in a US drone strike near Baghdad International Airport on January 3, 2020.
Iran maintains an advisory mission in Syria at the request of the Arab country with the aim of helping Damascus get rid of the foreign-backed militants who have been fighting the democratically-elected government there since 2011.
Earlier in December, Israel killed two Islamic Revolution Guards Corps (IRGC) military advisers – identified as Mohammad Ali Ataee Shoorcheh and Panah Taqizadeh – in an attack in Syria.
The IRGC announced in a statement at the time that the two officers were martyred against the backdrop of the relentless savagery of the “fake and child-killing” Israeli regime in Gaza.
