( CNN ) -- Iran 's supreme leader on Sunday blasted U.S. plans to overhaul the setup for a missile defense shield in Europe , calling the Obama administration 's intentions `` anti-Iranian , '' state-run media reported . Ayatollah Ali Khamenei says the U.S. president is following `` anti-Islamic and anti-Iranian '' policies . Ayatollah Ali Khamenei also called Western concerns about Iran 's nuclear ambitions -- which Tehran says are only for energy purposes -- `` purely a fabrication by the United States , '' according to the Islamic Republic News Agency . `` This is something that is in the doctrine of anti-Iranianism , since the policy and the 30-year-old history of the Islamic Republic has proven that Iran wants to live in peace and under the spirit of equality and fraternity , with its Muslim neighbors and the rest of the world , '' Ayatollah Ali Khamenei said . On Thursday , President Obama said the United States is significantly overhauling Bush-era plans for a missile defense shield in Europe , based partly on the latest analysis of Iran 's offensive capabilities . The `` new missile defense architecture in Europe '' will be ready faster , work with existing technology and provide better missile defense than the program proposed by former President George W. Bush , Obama said . Obama said the change of gears was based on an `` updated intelligence assessment '' about Iran 's ability to hit Europe with missiles . The Islamic republic 's `` short- and medium-range '' missiles pose the most current threat , he said , and `` this new ballistic missile defense will best address '' that threat . Khamenei , speaking on the first day of Eid al-Fitr , a festive end to the Muslim holy month of Ramadan , countered by comparing Obama to his predecessor . `` America , under its former president , spared no efforts against the Muslim world as well as against Iran , '' Khamenei said . `` Even the current administration -- with the apparently friendly words and messages -- follows that same anti-Islamic and anti-Iranian policy of the past . '' The Bush-era proposal called for the United States to set up a radar site in the Czech Republic and 10 missile interceptors in Poland to counter the threat of Iran launching long-range missiles at America 's allies in Europe . The new system will have `` hundreds '' of missile interceptors instead , a Pentagon official said last week . It also will have mobile radars , including some in space , `` that can move to wherever the threat actually emanates and wherever we feel we need to defend ourselves , '' said Gen. James Cartwright , vice chairman of the Joint Chiefs of Staff .
New U.S. plan is `` anti-Iranian , '' Khamenei says , according to state-run media . Obama : Change was based on updated assessment of Iran 's missile capabilities . IRNA : Khamenei says Western concerns over nuclear program `` fabrication '' by U.S .
