Iran is increasing security for the country's scientists and experts, following the assassination of a nuclear scientist last week, Iran's nuclear chief Ali Akbar Salehi was quoted as saying by semi-official news agency Press TV on Thursday.
"We have been pursuing serious protective measures for hundreds of our scientists and experts since last year and based on the recent decision, we are to increase protection measures multiple-fold and take other steps as well," Salehi said.
"Dr Shahriari was not alone at the time of the attack, he was under protection, but devil ways employed by enemies cannot be predicted," Salehi stated. "Dr Shahriari did not used to live in his own home and he was under protection somewhere else, but the terrorist attack came in twinkling of an eye," he continued.
"The enemy has found that Iran's nuclear work is advancing considerably and has turned into a symbol of power for Iranian nation. It makes efforts to withhold Iranian nation from the power, but they made a big mistake," added the Islamic Republic's nuclear chief.
