Iranian intelligence on Sunday released photographs of four suspects it claims are tied to the assassination of Mohsen Fakhrizadeh, head of the Iranian nuclear program, who was killed on Friday in a drive-by shooting outside Tehran.

Iran's Supreme Leader Ayatollah Ali Khamenei called Fakhrizadeh "the country's prominent and distinguished nuclear and defensive scientist" and has demanded the "definitive punishment" of those behind the killing.
Iranian police have distributed the photos across the country, as authorities launch searches for the four suspects.
Earlier on Sunday, Iran's Fars news agency published a report which claimed that the assassination had been carried out remotely, using a machine gun control mounted on a truck which self-destructed after the attack.
Iran has accused Israel of directing the assassination, calling the incident an act of "state-sponsored terrorism."
The Iranian parliament on Sunday held a closed-door hearing about Fakhrizadeh's killing. Afterward, parliament Speaker Mohammad Baqer Ghalibaf said Iran's enemies must be made to regret killing him.
"The criminal enemy does not regret it except with a strong reaction," he said in a broadcast on Iranian state radio.
A public session of lawmakers saw them chant: "Death to America!" and "Death to Israel!"
They also began the review of a bill that would stop inspections by the International Atomic Energy Agency. The nuclear watchdog has provided an unprecedented, real-time look at Iran's civilian nuclear program following the country's 2015 nuclear deal with world powers.
Iran's 290-seat parliament is dominated by hard-liners who likely would support the bill. It ultimately would have to be approved by Iran's Guardian Council. Khamenei also has final say on all matters of state.
