Abduction of the Iranian nuclear scientist, Shahram Amiri, was a terrorist move, Iranian Parliamentary Speaker Ali Larijani was quoted as saying by the Iranian Iribnews news agency.
At the sidelines of an open session of Majlis on Wednesday, Larijani told reporters that America and Saudi Arabia are responsible for missing of the scientist.
He reiterated that Americans have already carried out such terror moves while they were not responsible for their behaviors, the acts which are below the dignity of a country and human rights systems.
The top parliamentarian further said it was clear that the abduction was done by the Americans and with collaboration of Saudis, stressing the acts are harmful for their own reputation.
He added such an example could also be seen in the nuclear issue, when they disrupt an international system such as NPT.
Larijani stated when some decisions are made against regulations in the Board of Governors, it could simply disrupt international psychological tranquility.
"We have found documents that prove U.S. interference in the disappearance of the Iranian pilgrim Shahram Amiri in Saudi Arabia," Foreign Minister Manouchehr Mottaki said earlier.
Iran accused the United States of involvement in the disappearance of a technology university researcher "rumored" to be involved in Tehran's nuclear program.
