The Latest from Iran (20 December): Montazeri Death; Regime Scrambles for Legitimacy
1830 GMT: Clashes and Occupation (1). Back from a short break to find that Ahmad Montazeri, the son of the late Grand Ayatollah, has said "several people" were injured in clashes with security forces. Some of those forces are still "occupying" the Imam Hassan Mosque where services took place this morning.
1630 GMT: And Now the Lighter Side of the News. Beyond the significant events surrounding the funeral of Grand Ayatollah Montazeri, this revelation of the words of President Ahmadinejad's aide Esfandiar Rahim-Mashai in Copenhagen last week:
Iran is a creditor for the international community and the whole of the world is indebted to it. Because Iran is the most important of the founders of human society and urbanism. "We are a rich and resourceful country but our resources are not oil and gas, it is the Iranian culture. Today, because of a smart, witty and courageous son, Mr. Ahmadinejad, deceiving it [Iran] has become impossible.
Ahmadinejad is the manifestation of a well-informed, wise and passionate Iranian who has stood in front of international politics so that everyone understands that the path of Iran's development cannot be abandoned.
1600 GMT: We've started a second set of videos of today's events.
1555 GMT:Khordaad 88 has posted the video and English transcript of one of Grand Ayatollah Montazeri's last interviews, which was with Radio Zamaaneh on the subject of his 1989 split with Ayatollah Khomeini.
1520 GMT: Mardomak is reporting that the Montazeri family has cancelled the funeral reception because of conditions similar to "martial law" around their home.
1515 GMT: Back after a break --- thanks to Tricia Sutherland for minding the EA shop.
1325 GMT: Activists report that demonstrations and vigils in Tehran tonight for 8-10 p.m. local time (1630-1830 GMT) at Vanak Square, Vali-e Asr, 7 Tir, Mohseni, Azadi, and Enghelab.
1314 GMT: BBC Persian television is continuing to broadcast into Iran despite attempts by the regime to jam its signal.
1300 GMT: Among new videos from Qom and elsewhere in Tehran are chants "We will fight, we will never die, we will not accept oppression", "Dictator, shame on you, leave your monarchy", and "Dictator, dictator, Montezari is alive".
1243 GMT: Online new service reports that Qom police protected mourners and demonstrators from basijis and plain-clothed security forces, who destroyed Montezari banners.
1125 GMT: A Pause. We're taking a break for a bit to catch our breath. Please keep sending in information of anything we have missed and check out our videos and analysis.
1110 GMT: Mediawatch. The top story on the BBC website's is "Clashes reported at funeral of Iranian dissident cleric". In contrast, CNN has not updated its article to mention today's funeral, let alone consider its significance.
1100 GMT: Among the chants on videos from Qom: "Those who cheated tore up the photos [of Ayatollah Khomeini]"; "Political prisoners must be freed".
1010 GMT: Andisheh-ye No (New Thought), one of five papers warned this weekend for not paying due attention to "large" pro-Government rallies on Friday has been banned from publishing.
1005 GMT: Iran Mediawatch. It looks like Mehr News has defied the Government command to ignore the crowds for Montazeri. It has photos of the gathering and of prominent figures paying condolences. It may be a sign of demand for confirmation of events or, alternatively, Internet restrictions in Iran that Mehr's website appears to be overloaded.
0940 GMT: Images of Mourning. Photos have been posted of Mehdi Karroubi and Mir Hossein Mousavi paying their respects inside the Montazeri house. We have also posted the first videos of mass demonstrations in Qom and Najafabad.
0910 GMT: Press TV just posted a short report on the funeral of "leading clerical figure Ayatollah Hossein Ali Montazeri". It mentions the Supreme Leader's condolences, omitting the criticisms of Montazeri.
There is no mention, however, of the crowds in Qom.
0905 GMT: The View from the Other Site --- Montazeri & "Terrorists". One of the few remarks from an Iran-based commentator in non-Iranian media is in Al Jazeera English's coverage. It comes from Tehran University academic Seyed Mohammad Marandi:
[Montazeri said] the same thing for around 25 years....After his inner circle was discovered to be linked to Mujahidin terrorists based in Iraq, he was isolated by the reformists....He is not a major player and has always been very critical.
0855 GMT: Iranian Mediawatch. Press TV's website has nothing on the funeral (now see 910 GMT). The Iranian Labor News Agency's English site has a short item that "thousands of mourners converged" on Qom and that Mir Hossein Mousavi attended. ILNA also uses the title "Ayatollah" for Montazeri, who was "one of the leaders of the 1979 Iranian Revolution along with the founder of the Islamic Republic Imam Khomeini".
ILNA also emphasises, via the word of Montazeri's doctor, that the cleric died of natural causes.
0850 GMT: New Entries. We have posted the video and translation of an interview given by Grand Ayatollah Montazeri's son Saeed yesterday on his father's last words and views: "I think one of the main reasons [for his death] was his grief for the post-election events which troubled my father a lot."
And, on another front, we have posted a view from Tehran of the current Iranian position in the nuclear talks with the "West" and the International Atomic Energy Agency.
0840 GMT: Mir Hossein Mousavi's Kalemeh, in a long report on the funeral, confirms that both Mousavi and Mehdi Karroubi were in the procession.
0810 GMT: Montazeri's son has asked the crowd to quiet their chants, but the protests continue.
0805 GMT: Mediawatch. The Montazeri ceremonies/protests are now the lead item on the BBC, with Jon Leyne providing an excellent summary both of today's gathering and of attempted Government restrictions. Leyne says that Mir Hossein Mousavi and Mehdi Karroubi were in the funeral procession, a claim that we have been unable to confirm.
0735 GMT: With security forces apparently trying to move people from the Shrine, crowds are moving about Qom, with many reportedly headed toward Montazeri's house.
0730 GMT: The doors of the Masoumeh Shrine have been closed because of the size of the crowd.
0720 GMT: Numerous reports of the crowd's mourning turning into a protest with chants against the Government and even the Supreme Leader.
0657 GMT: It appears the ceremony proceeded more quickly than we first reported (0615 GMT). Reports now that Montazeri has been buried in the Massoumeh Shrine.
0650 GMT: The article in Time from Robin Wright, one of the best US-based journalists on Iran, is to the point: "Iran's Opposition Loses a Mentor But Gains a Martyr".
0643 GMT: Josh Shahryar has posted a tribute, "Good Bye Montazeri, You Will Be Missed": "The struggle for freedom, human rights and justice will continue. If we’ve learned anything in the past six months it is that the Iranian people’s desire for change will not die with the death of an individual – no matter how important that individual may be."
0640 GMT: Ayatollah Shobeiri-Zanjani is now leading prayers.
0630 GMT: A LiveBlog from Qom is claiming "hundreds of thousands" are now in the streets. Reported chant: "Montazeri is not dead; the Government is dead."
0615 GMT (0945 Tehran & Qom): The mourning ceremonies for Grand Ayatollah Hossein-Ali Montazeri began about 30 minutes ago in Qom, with his body being taken from his house to the Imam Hassan mosque. In about 45 minutes, the procession will move from the mosque to the Masoumeh Shrine. There are reports, despite Government efforts to limit or prevent attendance, tens of thousands have lined the route.
As well as the reported orders from the regime to Iranian newspapers to prohibit his photograph on front pages, to ignore Montazeri's political significance and emphasise the 1989 incident that led to his dismissal as Ayatollah Khomeini's successor, the Government is jamming BBC Persian.
