Iran-US rhetoric "raises spectre of war" but both still use intermediary talking channels

Trump has repeatedly threatened to intervene if Iran continued to kill protesters, but the countrywide demonstrations over economic privations and political repression have since abated. He has said the United States would act if Tehran resumed its nuclear program after the June airstrikes ‍by Israeli and U.S. forces on key nuclear installations. Iran has said it is ready to retaliate if needed. But according to FRANCE 24's Reza Sayah, speaking from Tehran, both parties are still talking through intermediary channels.
