TEHRAN (AFP/Reuters) - Iran lashed out at foreign governments on Friday accusing them of complicity in crimes and killings in the violent aftermath of the disputed re-election of President Mahmoud Ahmadinejad. The fresh anti-West salvo by Foreign Minister Manouchehr Mottaki comes a day after violent clashes between thousands of mourners and riot police in central Tehran and as the Islamic republic prepares to put around 30 protesters on trial on charges of rioting and vandalism. Western and European countries, with their overt and covert capabilities, interfered in Irans election... the worst among them being Britain, Mottaki was quoted as saying by the state broadcasters website. The countries who interfered through their television networks by telling how to instigate riots, build explosives and other tension creating activities are accomplices in all the committed crimes, murders and are held responsible. Iran has consistently blamed foreign countries for fuelling the post-election violence in Tehran in which officials say about 30 people died and several hundred were wounded. The ISNA news agency, meanwhile, said about 30 people will be put on trial in a revolutionary court on Saturday on charges of having participated in riots and acting against national security, disturbing public order and vandalising public and government property. The commander of Tehrans metropolitan police, Azizollah Rajabzadeh, said on Friday said it has arrested 50 demonstrators on Thursday in Tehran streets and at the Behesht-e Zahra cemetery south of Tehran, where people had gathered to commemorate those who died in election violence. In the biggest opposition show of force for three weeks, thousands of people had congregated at the two locations, witnesses said. Rajabzadeh said prominent film director Jafar Panahi was freed after being briefly held as he along with other mourners had gathered near the grave of Neda Agha-Soltan, a young woman whose death was caught on video and distributed on the Internet. Ayatollah Ahmad Janati, Irans cleric and head of the Guardians Council, the powerful electoral watchdog which upheld Ahmadinejads victory, on Friday blamed the deaths of protesters on Mousavi and reformist Mehdi Karroubi, who both stood unsuccessfully against Ahmadinejad. Yes, go and apologise to them (protesters) and tell them that we started a mutiny but you were killed. Accept this blame, because if there were no riots, nobody would have died. Meanwhile, President Mahmoud Ahmadinejad warned his political rivals on Friday that their efforts to drive a wedge between him and Supreme Leader Ayatollah Ali Khamenei would come to nothing. This is not a political relationship ... our relationship is based on kindness. It is like a relationship between a father and his son, Ahmadinejad said in a speech in the holy city of Mashhad. Your efforts will bear no fruit. This road is closed for those devils who dream about harming our relationship. Their dream will be buried along with them, state television reported. Hardline cleric Ahmad Jannati, head of Irans top legislative body, also criticised Ahmadinejad. Such appointments hurt your supporters ... A key position should not be given to a person who is not respected, Jannati told worshippers at Tehran University. His speech was broadcast live on state radio. Jannati said the vote was Irans healthiest since the revolution, adding Irans moderate defeated candidate Mirhossein Mousavi should go on trial for fomenting instability in Iran. Mousavi and other leading moderates say the vote was rigged, calling the new government illegitimate. You were behind these unrests. You are responsible for the bloodshed, Jannati said. Sooner or later you will be punished for your illegal and un-Islamic acts. We can not demand release of those criminals who have damaged public properties, created disorder and instability, Jannati said. But others should be freed.
