Some of those involved in the assassination of Iran's top nuclear scientist last month have been arrested, Hossein Amir-Abdollahian, an adviser to the Iranian parliament speaker, said on Tuesday, according to the semi-official news agency ISNA.
"The perpetrators of this assassination, some of whom have been identified and even arrested by the security services, will not escape justice," ISNA quoted Amir-Abdollahian as telling Iran's Arabic-language Al Alam TV.
Iran has blamed Israel for the assassination of Mohsen Fakhrizadeh, who was seen by Western intelligence services as the mastermind of a covert Iranian program to develop nuclear weapons capability. Tehran has long denied any such ambition.
On Monday, Tasnim, a semi-official news agency reported that the assassination was carried out remotely with artificial intelligence and a machine gun equipped with a "satellite-controlled smart system."
Israel has neither confirmed nor denied responsibility for the killing, but in the past has acknowledged pursuing covert, intelligence-gathering operations against the nuclear program of its arch-enemy Iran.
The Islamic Republic has given contradictory details of Fakhrizadeh's death in a daytime November 27 ambush on his car on a highway near Tehran.
"No terrorists were present on the ground...Martyr Fakhrizadeh was driving when a weapon, using an advanced camera, zoomed in on him," Tasnim quoted Ali Fadavi, the deputy commander of Iran's Revolutionary Guards, as saying in a ceremony on Sunday.

Senior Iranian officials have been making threats, suggesting that they will avenge the killing of Fakhrizadeh, causing Israel to take several defensive measures in anticipation of a possible Iranian retaliation. These include procedures for joint detection of missile or rocket fire at Israeli or American targets.
Fakhrizadeh, identified by Israel as a prime player in what it says is a continuing Iranian quest for a nuclear weapon, was the fifth Iranian nuclear scientist killed in targeted attacks since 2010 inside Iran, and the second slaying of a high-ranking Iranian official in 2020.
The commander of the Revolutionary Guards' elite Quds Force, Qassem Soleimani, was killed in a U.S. drone strike in Iraq in January. Tehran retaliated by firing missiles at U.S. military targets in Iraq.
