(irna) -- Qasemi made the remarks in reaction to the White House statement on Friday in which the country demanded freedom of a US citizen who has been charged of spying in Iran.
Iran’s Judiciary apparatus, courts and judges similar to other democratic systems are independent and act based on domestic rules and in the framework of separation of power branches, the official added.
He said that Iran’s judicial apparatus observes any act against the country’s national security.
The US officials' and institutions' threatening statements will not effect Iran’s judicial system commitment to examine and punish those who violated the country’s rules and acted agaisnt the national security, Qasemi added.
He said those who have been listed in the White House statement have been impeached for charges and their case will be examined in the competent courts.
The spokesman referred to Robert Levinson's case and said Iran has told the American officials for several times that Levinson has left Iran and Tehran has no new information about him.
The US threatening rhetoric has roots in the hegemonic nature of the country and the Iranian nation has a longstanding record of countering such hostile actions, he added.
Qasemi said the Islamic Republic will not accept the US' oppressive behavior and Washington should talk to the Iranian nation with respect and dignity.
He recalled Washington's breach of its obligations and called for immediate freedom of Iranian prisoners who have been jailed in the US for false reasons.
The US should abandon prosecution of Iranian citizens who are residing in other countries, the spokesman added.
