TEHRAN (AFP) - Irans former foreign minister Manouchehr Mottaki has hit out at his sacking this week by President Mahmoud Ahmadinejad, branding the move both un-Islamic and offensive. Sacking a minister while (he is is) on a mission un-Islamic, undiplomatic, offensive and outside the practices of politics, Mottaki was quoted as saying by the Mehr news agency on Sunday. Ahmadinejad announced his decision to oust Mottaki on Monday while the 57-year-old career diplomat was on an official visit to Senegal. I was never told about the appointment of a new person within 24 hours of my departure for the mission, Mottaki said, referring to a meeting he had with the president on the eve of his departure, Mehr reported. The countrys atomic chief Ali Akbar Salehi officially took over on Saturday as the Islamic republics interim foreign minister at a function which was also a farewell ceremony for Mottaki who shunned the reception. What is more ridiculous is that (I was not told about) the date for the farewell ceremony and the introduction of Salehi, Mottaki said. Responding to his remarks, a top aide to Ahmadinejad reiterated the government line that Mottaki had known in advance about his dismissal. Mr Mottaki was told about the change last Saturday, and he too expressed his readiness to be replaced, senior adviser Mojtaba Samareh Hashemi was quoted as saying by the ISNA news agency. Parliament speaker Ali Larijani on Sunday criticised Ahmadinejads move, saying it had led to inappropriate judgments of the situation inside Iran. If the intention was to replace the foreign minister, it was only right to do it tactfully and respectfully with regards to the minister, not when (he is) travelling, which fuels inappropriate interpretations of the countrys situation, ISNA quoted Larijani as saying. Mottaki was sacked after he hailed as a step forward remarks by US Secretary of State Hillary Clinton that Tehran is entitled to a peaceful nuclear energy programme. Clinton had told the BBC that Iran could enrich uranium for civilian purposes in the future, but only once it has demonstrated it can do so in a responsible manner and in accordance with Tehrans international obligations. Mottaki appeared to cut across Irans official position repeated almost daily that the countrys enrichment of uranium is non-negotiable. His sacking also came just days after Iran held crunch talks in Geneva on December 6 and 7 with world powers over its controversial nuclear dossier. Further talks are scheduled for next month in Irans neighbour Turkey.
