A top Iranian nuclear official says a U.N. report has "vindicated" his country's nuclear program as a peaceful one.

The semi-official Iranian news agency Fars quotes Ali Asghar Soltanieh Saturday as saying Iran will resist political pressure to give up its nuclear goals.

The International Atomic Energy Agency released a report Friday saying Iran has allowed its inspectors greater access to its main nuclear complex in the city of Natanz.  But the report said Iran failed to reveal if its nuclear program includes a military component.

Soltanieh, Iran's envoy to the U.N. nuclear agency, said Iran will cooperate with inspections but not beyond its legal obligation.

The U.S. State Department on Friday accused Iran of failing to meet its obligation by not proving that its nuclear program is being developed solely for peaceful purposes.

Western nations accuse Iran of trying to enrich uranium to build a nuclear bomb, but Tehran says it is pursuing nuclear energy.

Next Wednesday, representatives from the five permanent members of the U.N. security council, as well as Germany, will meet in Frankfurt to discuss whether to impose harsher U.N. sanctions on the Islamic republic.
