Iranian state media reported Iran's delegation left US-Iran talks that began early on June 21 in Switzerland in protest over comments made by US President Donald Trump.
The talks, mediated by Qatar and Pakistan, lasted 80 minutes and focused on implementing a memorandum of understanding between Tehran and Washington, according to officials from both sides.
Members of the Iranian negotiating team said the talks also addressed the situation in Lebanon and did not include discussions on Iran's nuclear programme.
Iranian negotiators also said broader negotiations would not proceed if the war in Lebanon continues. Meanwhile, chief negotiator Mohammad Bagher Ghalibaf warned that US should be careful with their statements as Iran's armed forces are prepared to respond to any threats.
