May 1 (Reuters) - The United States never confirmed its participation in a fourth round of Iran talks on Saturday in Rome, a source familiar said on Thursday after reports said the negotiations were postponed.
The source told Reuters that the timing and venue of the next round of talks have yet to be confirmed but are expected in the near future. Oman said earlier in the day that the next round of U.S.-Iran nuclear talks that it said were provisionally planned would be rescheduled for logistical reasons.
