Weekend talks between US and Iran end without agreement on uranium enrichment

Weekend negotiations between the United States and Iran concluded without reaching an agreement, according to media reports. The talks reportedly focused on American demands for Iran to halt uranium enrichment activities for a 20-year period. The discussions represent part of ongoing diplomatic efforts to address Iran's nuclear program, which has been a source of international concern and sanctions. The failure to reach an accord continues the stalemate over Iran's nuclear activities and suggests further diplomatic challenges ahead in resolving the nuclear standoff.
