Erdogan said that Turkey voted "no" to UN Security Council's sanctions against Iran, because Turkey, Iran and Brazil signed a nuclear swap deal.
"If we had not said 'no' to sanctions, we would have denied ourselves. It would be a dishonor. We would not want to participate in such a dishonor because history will not forgive us, " he said.
On Wednesday, Iranian President Mahmoud Ahmadinejad said the resolution against Iran "worth nothing," the semi-official ISNA news agency reported.
Iranian Foreign Minister Manouchehr Mottaki told the semi- official Fars news agency on Wednesday that the decision by the UN Security Council is "a move backward."
