Russian Deputy Foreign Minister Gennady Gatilov said imposing new sanctions against Tehran is not possible adding that there is no reason to intensify sanctions against Iran. Gatilov pointed out on Friday that imposing more sanctions against Iran and putting forward issues such as possible attack against Iran are considered as interfering acts with the aim of regime change, Russian News Agency Interfax quoted Galitov as saying. He underlined his country\'s obligation to its stance on opposing unilateral sanctions of the west against Iran and said that such sanctions are out of framework of the UN Security Council resolutions. He added that whatever is proposed in the UN Security Council out of framework of resolutions against Iran, has no connection with consolidating system to none proliferation of nuclear arsenal. Gatilov continued that currently there is no discussion about beginning uranium enrichment in Iran at the UN Security Council. \'Tehran has informed International Atomic Energy Agency (IAEA) about its intention to start enriching uranium in its center at Frodo on time and nuclear materials in this center are under control of the agency and this fact should not be ignored,\' the Russian official said. In recent days, Russia had strongly opposed to imposing new economic sanctions against Iran. Russian Deputy Foreign Minister and senior negotiator for nuclear affairs Sergey Rybakov clearly declared his country\'s opposition to oil sanctions against Iran.
