President Obama says the United States has begun talks with its international partners about Iran’s failure to accept a proposed nuclear agreement. The president said that a number of possible steps will be developed over several weeks. He told reporters in Republic of Korea Thursday that the aim of the steps would be to send a clear message to Iran. Mr. Obama also said he continues to hope that Iran will decide to accept an international plan for the country’s nuclear program. Under the plan, Iran would send its uranium to other countries for enrichment. A European Union official says international powers will meet in Belgium Friday to discuss Iran.
