Jerusalem, Jun 19:  Talks between the US and Iran were called off on Friday after intense fighting between Israel and Hezbollah in southern Lebanon, three officials said, raising questions about a nascent agreement to end the war in Iran. Iranian officials didn't travel as planned to Switzerland, insisting that the fighting in Lebanon must stop before the talks can take place, according to the officials, who spoke on condition of anonymity to discuss the ongoing mediation to try to get the talks rescheduled. US Vice President JD Vance also cancelled his trip.
