"Our intelligence and security forces have identified nearly 40 Americans who have ordered, assisted and collaborated in the assassination, and a number of others, including the US drone operators (that have conducted the attack) are yet to be identified, which will be done soon," Deputy Foreign Minister Mohsen Baharvand said.
He added that the foreign ministry and the judiciary have coordinated their efforts to pursue the case more rapidly and identify the American and non-American individuals and parties involved in the assassination to start litigation against them.
Baharvand said that in addition to those involved in the crime, the US government and several countries whose territories have been used to assassinate General Soleimani should account for their actions that have been made in violation of the international laws.
"We will pursue the case at international bodies and organizations," he said.
Iran announced on Monday that it has issued arrest warrants for 36 officials of the US and other countries who have been involved in the assassination of the martyred Commander of the Islamic Revolution Guards Corps (IRGC) Quds Force, Lieutenant General Qassem 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.
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.
