Iran threw a retaliation threat over the assassination of its top nuclear scientist Mohsen Fakhrizadeh the reports says Israeli embassies are on alert, says the report. Iranian supreme leader Ayatollah Ali Khamenei informs about "punishing" the criminals behind Mohsen Fakhrizadeh's killing on Saturday. Iran President Rouhani had earlier accused Israel of acting as a "mercenary" for the United States. 

"The nation of Iran is smarter than to fall in the trap of the conspiracy set by the Zionists. They are thinking of creating chaos, but they should know that we have read their hands and they will not succeed," Rouhani said as he promise not to "leave this criminal act unanswered" and asserted that Iran will retaliate "in due time". The nuclear scientist, Mohsen Fakhrizadeh, 59, was shot by assailants in his car near Tehran and died in hospital. Iran foreign minister Mohammad Javad Zarif doubtedly said that there were "serious indications of an Israeli role", soon after the assassination. He adds, "this cowardice with serious indications of Israeli role shows desperate warmongering of perpetrators."

On the other side, US had issued sanctions against Fakhrizadeh in 2008 for "activities and transactions that contributed to the development of Iran's nuclear programme". Iran's defence minister Amir Hatami quotes Fakhrizadeh's assassination and the killing of Iran's top general Qasem Soleimani were "completely related" incidents. Iran's armed forces chief Major General Mohammad Bagheri described the assassination a "a bitter and heavy blow to the country's defence system" and warned of "severe revenge".
