DUBAI, United Arab Emirates >> An Iranian scientist that Israel alleged led the Islamic Republic’s military nuclear program until its disbanding in the early 2000s was killed in a targeted attack that saw gunmen use explosives and machine gun fire today, state television said.

Iran’s foreign minister alleged the killing of Mohsen Fakhrizadeh bore “serious indications” of an Israeli role, but did not elaborate.

Israel declined to immediately comment, though Israeli Prime Minister Benjamin Netanyahu once called out Fakhrizadeh in a news conference saying: “Remember that name.” Israel has long been suspected of carrying out a series of targeted killings of Iranian nuclear scientists nearly a decade ago.

The killing risked further raising tensions across the Mideast, as just a year ago Iran and the U.S. stood on the brink of war. It comes just as President-elect Joe Biden stands poised to be inaugurated in January and likely complicates his efforts to return America to the Iran nuclear deal.

State TV said Fakhrizadeh was attacked by “armed terrorist elements.” He died at a local hospital after doctors and paramedics couldn’t revive him.

The semiofficial Fars news agency, believed to be close to the country’s Revolutionary Guard, said the attack happened in Absard, a small city just east of the capital, Tehran. It said witnesses heard the sound of an explosion and then machine gun fire. The attack targeted a car that Fakhrizadeh was in, the agency said.

Others wounded, including Fakhrizadeh’s bodyguards, also were taken to a local hospital, the agency said.

State television on its website later published a photograph of security forces blocking off the road. Photos and video shared online showed a Nissan sedan with bullet holes in the windshield and blood pooled on the road.

No group immediately claimed responsibility for the attack. However, Iranian media noted the interest that Netanyahu had previously shown in Fakhrizadeh. Iranian Foreign Minister Mohammad Javad Zarif on Twitter also pointed a finger at Israel, calling the killing an act of “state terror.”

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

Hossein Salami, chief commander of the paramilitary Guard, appeared to acknowledge the attack on Fakhrizadeh.

“Assassinating nuclear scientists is the most violent confrontation to prevent us from reaching modern science,” Salami tweeted.

Hossein Dehghan, an adviser to Iran’s supreme leader and a presidential candidate in Iran’s 2021 election, issued a warning on Twitter.

“In the last days of their gambling ally’s political life, the Zionists seek to intensify and increase pressure on Iran to wage a full-blown war,” Dehghan wrote, appearing to refer to U.S. President Donald Trump. “We will descend like lightning on the killers of this oppressed martyr and we will make them regret their actions!”

The killing comes just days before the 10-year anniversary of the killing of Iranian nuclear scientist Majid Shahriari, which Tehran also blamed on Israel. Those targeted killings came alongside the so-called Stuxnet virus, believed to be an Israeli and American creation, that destroyed Iranian centrifuges.

The area around Absard is filled with vacation villas for the Iranian elite with a view of Mount Damavand, the highest peak in the country. Roads today, part of the Iranian weekend, were emptier than normal due to a lockdown over the coronavirus pandemic, offering his attackers a chance to strike with fewer people around.

Fakhrizadeh led Iran’s so-called “Amad,” or “Hope” program. Israel and the West have alleged it was a military operation looking at the feasibility of building a nuclear weapon in Iran. Tehran long has maintained its nuclear program is peaceful.

The International Atomic Energy Agency says Iran “carried out activities relevant to the development of a nuclear explosive device” in a “structured program” through the end of 2003. That was the Amad program, which included work on the carefully timed high explosives needed to detonate a nuclear bomb.

Iran also “conducted computer modeling of a nuclear explosive device” before 2005 and between 2005 and 2009, the IAEA has said. The agency said, however, that those calculations were “incomplete and fragmented.”

IAEA inspectors now monitor Iranian nuclear sites as part of Iran’s now-unraveling nuclear deal with world powers.

Netanyahu in 2018 gave a presentation in which he unveiled what he described as material stolen by Israel from an Iranian nuclear archive.

“A key part of the plan was to form new organizations to continue the work,” Netanyahu alleged in 2018. “This is how Dr. Mohsen Fakhrizadeh, head of Project Amad, put it. Remember that name, Fakhrizadeh.”
