WASHINGTON, Aug. 15 (Xinhuanet) -- The United States reiterates on Monday that it will work closely with the EU-3 - Britain, France and Germany - to resolve Iran's nuclear issues.

    "The US approach to this issue is to work very closely and in a supportive manner with the EU-3 countries...to get Iran to abide by its international commitments, including to the commitment it made in the Paris Accord," State Department spokesman Sean McCormack said.

    "If the IAEA (International Atomic Energy Agency) does not find that Iran has lived up to its commitments, then we expect the next step would be to go to the Security Council... That's the route that we're working on," McCormack said.

    The State Department spokesman made the remarks two days after US President George W. Bush said he could consider using force as a last resort against Iran if it refuses to comply with international demands to halt its nuclear program.

    In an interview with Israeli TV, Bush said that if diplomacy on Iran's nuclear issue fails, "all options are on the table."

    "The use of force is the last option for any president...we've used force in the recent past to secure our country," Bush said.

    After rejecting the European offer, Iran resumed uranium conversion at its nuclear facility in Isfahan on Aug. 8. The IAEA responded with a resolution calling on the Iranians to again put the process on hold.

    The United States accuses Iran of trying to produce nuclear weapons, but Tehran insists its nuclear program is entirely peaceful. Enditem
