Secretary of State John Kerry is warning Iran to come to upcoming nuclear talks prepared to deal seriously with world powers about addressing concerns over its nuclear program.
Speaking to reporters at the State Department on Friday, Kerry said Iran knows full well what it needs to do to prove its nuclear intentions are peaceful as it claims. If it does, he said the international community is prepared to respond positively. If not, he says it will only face increased international isolation. He said the choice is purely up to Iran. (AP)
