The United States temporarily suspended sanctions on Iranian oil on Monday after Vice President JD Vance said Iran would let UN nuclear inspectors return to the country, following talks in Switzerland. Last week, Tehran and Washington signed a memorandum of understanding laying the groundwork for the negotiations, after nearly 40 days of fighting that was followed by a shaky and often-broken ceasefire. Officials said conditions had been set for 60 days of technical talks to begin, again in Switzerland, to secure a long-term settlement.
