1855 GMT: HomyLafayette has an excellent summary of information around the Mohammadi case.
1845 GMT: More on the Trial of the Baha'i (see 0725 GMT). An EA reader notes confusion over the court hearing for seven Baha'i members arrested in 2008 for "organizing riots". Many accounts say the trial was today but one Iranian source reports that testimony began yesterday, a day early.
1815 GMT: Not A Nuclear Scientist. A highly reliable EA source checks in on the Professor's case: "I hand checked all three UN black lists [of Iranian nuclear scientists]. Ali Mohammadi isn't there."
1810 GMT: Mothers of Mourning Update. Norooz reports that 14 of the mothers arrested in last Saturday's protest have been transferred to Evin prison while the rest have been released.
An Iranian activist is claiming, however, that all mothers have been freed.
1800 GMT: Oh. My. Goodness. The Supreme Leader's representative to the Islamic Revolution Guard Corps, Ali Saeedi, has reportedly declared that the the deaths of 75,000 people will be worthwhile if the Islamic Republic is preserved. 1745 GMT: The Presidential website has made a contribution to the Mohammadi story, declaring that the Iranian nation will have its "revenge" on the "enemies" who killed the professor. More info, however, on Mohammadi as a particle physicist: his faculty profile and a list of publications which complements those we noted earlier (1445 GMT).

1630 GMT: Rah-e-Sabz is reporting an explosion in Shariati Street, Tehran, which has killed one person.
1605 GMT: How the Mohammadi Story Was Clarified. It should be noted that the "Iranian blogger" mentioned at 1250 GMT, with the post which began to establish that Professor Mohammadi was a particle physicist and not a nuclear scientist, was one of Mohammadi's students.
1555 GMT: We've posted a video showing how Iran's state media are framing the killing of Professor Mohammadi. It is, according to Tehran University academic Seyed Mohammad Marandi, a "terrorist" act --- probably the Mujahedin-e-Khalq (MKO) --- supported by the US and Israel.
1535 GMT: Not A Nuclear Scientist. The Iranian Atomic Energy Agency has formally denied any professional relationship with Professor Mohammad Ali Mohammadi. We also have another link for Professor Mohammadi: his involvement in the project "Synchrotron-light for Experimental Science and Applications in the Middle East" (SESAME).
1515 GMT: Curbing the Reformists. A group of members of Parliament has asked Speaker Ali Larijani to remove Ali Akbar Motashami, head of Mehdi Karroubi's Presidential campaign, as the chair of Committee for the Defense of Palestine. Motashami has criticised the outcome of the Presidential election since the day after the vote, and his Parliamentary opponents have claimed that he is responsible for the slogan, "No Gaza! No Lebanon! We Sacrifice for Iran!". Motashami was former Minister of Interior when Mir Hossein Mousavi was Prime Minister.
1510 GMT: Motahari's Move. High-profile member of Parliament (and brother-in-law of Ali Larijani) Ali Motahari has continued his recent criticism of the Ahmadinejad Government through a letter to Hossein Shariatmardari, the editor of the pro-Ahmadinejad newspaper Kayhan. Motahari declared that the President started the political crisis when he accused all of the candidates in the election of being "spinning tops" of Hashemi Rafsanjani. Motahari put four questions to Shariatmardari, including the reason why Ahmadinejad attacked Hashemi Rafsanjani in pre-election debates, and he concluded the letter, "Maybe you and your colleagues need a rest". Indeed, it would be better for Iranian society if Shariatmardari and his friends went "for a holiday in an enjoyable place" and allowed the situation to improve.
1505 GMT: The Attack on Rafsanjani. Cleric Hamid Rohani has announced that former President Hashemi Rafsanjani is "not a very important man" and asserted that Imam Khomeini believed Rafsanjani could be "deceived" by others.
1455 GMT: Makhmalbaf Puts Out Mousavi's Message? The filmmaker Mohsen Makhmalbaf, who is closely connected with Mir Hossein Mousavi, has set out a series of declarations, defining the state of the Green movement, in an interview:
Who are main leaders of the movement? It's the young generation. In each alley, in each street, you will see one smart youth lead 10 others. We have some famous people everywhere, but even if the government kills all of them, this movement will continue.
Makhmalbaf added a specific declaration on methods, "The past seven months have been the first time that we could ask people to think about non-violence. We are going to kill dictatorship, not dictators. We don't want to empty the prisons and then fill them with other people." The filmmaker also repeated his wish for "targeted sanctions" against the Islamic Revolution Guard Corps.
1445 GMT: More on the Particle Physicist. A fellow physicist has posted a link to 40 listed academic papers of "M. Alimohammadi" or "Mohsen Alimohammadi". None of them, according to the sources, are connected with nuclear physics.
1305 GMT: The Mohammadi Blame Game. Press TV, after carrying the message of Iran's Foreign Ministry of "signs of the involvement of the Zionist regime [Israel], the US and their allies" in the killing of Professor Mohammadi, rolls out the latest accusation
A terrorist group, whose radio station broadcast from the United States, took responsibility Tuesday for the fatal attack on an Iranian nuclear scientist in Tehran. The Iran Royal Association, an obscure monarchist group that seeks to reestablish the Pahlavi reign in Iran, announced in a statement that its "Tondar Commandos" were behind the assassination of Masoud Ali-Mohammadi.
And very quickly the "Iran Royal Association" denies the allegation.
1250 GMT: The Real Professor Mohammadi? A highly-reliable EA source provides the following important information:
I knew Ali Mohammadi personally and talked to him at length in Tehran in March. Almost certainly he had nothing to do with Iran's nuclear programme, according to very informed sources, and he was indeed a supporter of the Green movement. Rah-e-Sabz has published his signature on a letter sent by a group of university professors in support of Mousavi.
An Iranian blogger makes similar points, while adding that Mohammadi was a specialist on particle physics and linking to his Tehran University profile.
1050 GMT: The Battle over the Dead Professor. Wow, this is going to get heated. Ayande News , considered close to former President Hashemi Rafsanjani, has fought back against state media's portrayal that Massoud Mohammadi was a "dedicated revolutionary" killed by "anti-revolutionary" elements with the reminder that Mohammadi was publicly identified as a supporter of Mir Hossein Mousavi. The Mousavi site Kalameh also pushes this line and adds that Mohammadi, one of the first Ph.D. graduates in physics at Tehran University, was instrumental in the development of the programme over the last 20 years. (English summary)
0930 GMT: Killed Professor in Iran's Nuclear Programmme? The Internet chatter that Massoud Mohammadi, the Tehran University professor killed in an explosion this morning (see 0720 GMT), is a nuclear physicist now appears to be confirmed. Tehran Prosecutor General Abbas Jafari Doulatabadi has said that Mohammadi was a member of the country's "scientific elite" killed by Iran's enemies. (English summary in Los Angeles Times)
[NOTE: This update has been eclipsed by later news. It appears that the "nuclear physicist" claim is a line put out by Iranian authorities and does not represent Mohammadi's work.]
0920 GMT: Trials for US Citizens? The Iranian Foreign Ministry has repeated this morning that the three American citizens detained this summer when they crossed on foot into Iran from Iraq will soon be in court: "The judiciary will make a decision and we know that they will be tried soon." (Original story from Fars)
0750 GMT: A Cyber-Attack Too Far? Remember the "Iranian Cyber-Army", the group that carried out attacks on Twitter and, more importantly, the opposition website Mowj-e-Sabz? Well, they're back with a curious operation. This morning, their "diversion" attack posted their images and slogans on Baidu, China's top search engine. Baidu is now back in operation, but news of the hijacking has quickly spread. More importantly, so has the head-scratching. Why, given Tehran's need for Chinese support on a number of issues, would an Iranian group take down a prominent site accepted by the Chinese Government? If the Iranian Cyber-Army is close to the Government, someone has authorised a very stupid operation. If, on the other, the ICA is just a private group carrying out a bit of damage and silliness, it is not really helping anyone.
0745 GMT: Free the Mothers of Mourning. Amnesty International has called on Iran's authorities to release 33 Mothers of Mourning and their supporters, detained at the weekly protest in Laleh Park on Saturday.
0740 GMT: Nuclear Talks. US Secretary of State Hillary Clinton confirmed, after discussion of further US sanctions and Iran's latest proposals, that talks of the "5+1" powers (US, UK, France, Germany, China, Russia) on Tehran's nuclear programme will take place in New York at the end of this week.
0725 GMT: Blaming the Baha'is. A story that we should have noted this weekend. The Iranian regime will soon try seven leaders of the Baha'i faith, held in Evin prison since spring 2008. While the detentions occurred two years ago, the handling of the cases is now clearly tied to the Government's manoeuvres in the post-election crisis, blaming groups like the Baha'i, "terrorists", and foreign powers for the conflict. Tehran Prosecutor General Abbas Jafari Doulatabadi declared:
These people were not arrested because they were Baha'is....In searching their homes, a number of weapons and ammunition were discovered....[They] played a role in organizing the riots and sending pictures of the riots abroad. That is why they were arrested.
0720 GMT: Press TV is reporting that Dr Massoud Mohammadi, a Tehran University professor, has been killed near his home by the explosion of a booby-trapped motorbike. Mohammadi recently presented a paper on water resource management at an Australian conference. 0715 GMT: We begin today with two analyses. After yesterday's major development, the issuing of statements by Mehdi Karroubi and Mohammad Khatami, we put the question, "How Far Do The Green Movements Go?" in their demands. And amidst the recent discussion of #IranElection and Twitter, Christopher Parsons busts some fears and dispels some myths about Iran and social media.
