NPOV
I have tagged this article as POV because it is filled with sentences like "The Iranian Government security forces opened fire on protesters on the Shi'a holy day of Ashura, a day "symbolically about justice" and during which any kind of violence is forbidden," "Irregularities during the 2009 Iranian presidential election caused resentment among many Iranians," "outspoken political dissenters were detained.[5][6] However, dissenters continued to speak out against the Government, leading to further protests in December 2009" and "Security forces opened fire on the day of Ashura, the Shiite holy day "symbolically about justice", a day which any kind of violence is forbidden," which do not sound neutral or objective but like outright propaganda? 

Than in the protest section, rather than reporting the events objectively, quotes are used, not from people, but from pro-reformist articles, the result: "Protesters in Tehran gathered  "From Imam Hussain Square to Freedom Square", "from east to west along Revolution Street", and it was on this day that "the political and religious symbology of Iran's Islamic regime was turned on its head".[10] The protesters made another symbolic move- a "symbolic journey from a square named after its most revered hero toward a monument dedicated to freedom, along a street called Revolution."[10]" is unbelievably POV, this should be immedietly changed to a proper written text which reports everything objectively. Meanwhile in the part about the demonstrations condemning the Ashura riots (which BTW, where much larger than the Ashura riots themselfes - a fact which was completely ignored by the writers of this wiki article), "On December 30, counter-rallies staged and organized by the government at various cities, including Tehran, Qom, Arak, Shiraz and Isfahan called for the death of the protesters, with government workers receiving the day off work in order to attend the demonstrations" the sentence "with government workers recieving the day off work in order to attend the demonstrations, was added in such POV manner and clearly to discredit those demonstrations.

Now although it is mentioned how rioters set fire cars, shops, banks and power stations (though other vandalism by the rioter isn't mentioned at all), this is such small part of the article. The violence by rioters (against people) is not mentioned at all, meanwhile there is a complete section devoted to alleged government violence against the protestors. The article is also clearly written with a goal of reporting only what is good for the green movement, this is illustrated not only by the POV quotes but by for isntance the way that whenever government claims are reported, they are immedietly rebuffed with other POV claims, leading me to believe they were only included to "expose" the government as liars (which is POV). An example is "Although official sources in Iran denied involvement of security forces in killing of protesters, at least one amateur video shows, the security truck which was deliberately running over the protesters.[16] Other evidence says that security forces were armed with guns and shot at protesters, including one amateur video showing a plainclothes security force directly shooting at protesters.[17]," with source 16 being non-existant and source 17 being a vehimently anti-Iranian blog showing a video of a gunman, of which there is no proof he is associated with the police of basij. In the article he is however labelled as a "plainclothes security force." All in all, this article definetly needs to be re-written.
