Iranian citizens in Tehran are taking to the streets to are burning Israeli and American flags in protest over the assassination of the country’s top nuclear scientist, Mohsen Fakhrizadeh.

Protests were also reported in the cities of Mashhad and Qom, where footage provided by the Iranian Students News Agency (ISNA) showed demonstrators burning flags and burning photos of US President Donald Trump and the projected president-elect, Joe Biden.

​On Friday night, a small demonstration broke out in Tehran outside President Hassan Rouhani’s residence, with protesters shouting “no to submission, no to concession with America, only war with America,” the New York Times reported.

​Accordingly, videos shown on Iranian TV and posted to social media channels showed people holding signs that read “silence is permission for more assassinations” and “Mr. President, they killed your minister’s adviser. Stop negotiation.”

The attack on Fakhrizadeh, whom Israel had suspected of heading a secret Iranian military unit working on nuclear weapons, came ahead of the 10-year anniversary of the killing of Iranian nuclear scientist Majid Shahriari. That attack had also been blamed by Iran on Israel, as well as a spate of other targeted killings.

Israel has long accused Iran of secretly developing nuclear weapons, despite Iran dismissing these allegations, insisting that its program is peaceful.
