"Is the international community able to counter the US regime's expansionist and unilateralism?" Kadkhodayee wrote on his Twitter account.
"The assassination of General Qassem Soleimani, anti-terror commander of the Quds Force of the Islamic Revolution Guards Corps by the United States, which was recognized by the UN Special Rapporteur as a violation of international law, was a criminal act that unfortunately was accompanied by the silence of some international forums," he added.
In an interview with Reuters on Tuesday, UN Special Rapporteur Agnes Kalamar called the US crime of assassinating General Soleimani a violation of international law and called on countries to respond to targeted assassinations with military drones and to establish regulations in this area.
Lieutenant General Soleimani was assassinated in a US drone strike on Baghdad International Airport in Iraq on January 3.
The airstrike also martyred Deputy Commander of Iraq's Popular Mobilization Forces (PMF) Abu Mahdi al-Muhandis. The two were martyred in an American airstrike that targeted their vehicle on the road to the airport.
Five Iranian and five Iraqi military men were martyred by the missiles fired by the US drone at Baghdad International Airport.
Iran announced in late June that it had issued arrest warrants for 36 officials of the US and other countries who have been involved in the assassination of the martyred General Soleimani.
"36 individuals who have been involved or ordered the assassination of Hajj Qassem, including the political and military officials of the US and other governments, have been identified and arrest warrants have been issued for them by the judiciary officials and red alerts have also been issued for them via the Interpol," Prosecutor-General of Tehran Ali Alqasi Mehr said.
He said that the prosecuted individuals are accused of murder and terrorist action, adding that US President Donald Trump stands at the top of the list and will be prosecuted as soon as he stands down presidency after his term ends.message end/
