“Undoubtedly, this horrific terrorist incident is due to the inability of the sworn enemies of the Iranian nation against the scientific movement and the honors and capabilities of the great nation of Iran,” said Hassan Rouhani, the president of Iran.

Rouhani underlined that the killing of those such as Mohsen Fakhrizadeh will not disrupt the will of the youth and scientists of Iran to follow the path of accelerated scientific growth.

Chief of the General Staff of Iran Armed Forced Major General Mohammed Bagheri said that a severe strike awaits the perpetrators to avenge the assassination of Mohsen Fakhrizadeh.

“Terrorist groups and the leaders and the perpetrators of this cowardly attempt should know that severe revenge awaits them,” Bagheri said.

Iranian Foreign Minister Javad Zarif accused the Zionist regime of involvement in the killing of the scientist.

“Terrorists murdered an eminent Iranian scientist today. This cowardice—with serious indications of Israeli role—shows desperate warmongering of perpetrators,” Zarif tweeted.

He also calls on int'l community—and especially EU—to end their shameful double standards & condemn this act of state terror.

On Friday, Fakhrizadeh was ambushed while traveling in a vehicle on a rural road in Absard, a city near Tehran.

The attack was initiated when a truck carrying explosives hidden beneath a load of wood detonated near Fakhrizadeh's car. A second vehicle was destroyed with a bomb. Fakhrizadeh's bodyguards then clashed with gunmen.

Iranian sources reported that three to four of the attackers were killed while Fakhrizadeh's bodyguards and family members were also injured in the attack.

There were also reports of a suicide attacker who later died from his injuries.

Fakhrizadeh was taken to a hospital where he died after efforts to resuscitate him failed.
