TEHRAN, Jan. 17 (Xinhua) -- Tehran's Governor-General Morteza Tamaddon said Sunday that Iran is planning to boost security measures to shield its nuclear scientists from potential terror attacks by the enemies, the semi-official Fars news agency reported.
The announcement came following Iranian physicist Massoud Ali-Mohammadi, contradictorily referred to as a nuclear scientist, was killed Tuesday when a bomb strapped to a parked motorcycle was triggered by remote control outside his home in Tehran.
Prior to the attack on Ali-Mohammadi, "a series of arrangements and measures were in place to protect the nuclear scientists, which have now been boosted," Fars quoted Tamaddon as saying.
Iran's Foreign Ministry has said that there were traces of U.S. and Israeli involvement in the terror attack on Ali-Mohammadi, according to state IRIB TV.
