US and Iranian senior negotiators are holding a second day of talks aimed at reaching a permanent end to the war between the two countries, according to multiple reports. Coverage describes the first day of mediation as having a “rough” or rocky start, after which the parties move into a further round of discussions. The talks are presented as an effort to solidify the terms of a long-term settlement rather than a short-term pause. One outlet reports that negotiators complete a lengthy round of initial talks on Monday and move through the second day’s engagement within the same overall negotiation process. Another source emphasizes that the second day is scheduled as the next step after the first day’s setbacks. Across the reports, the common elements are that the US and Iran are represented by senior negotiators, that the discussions are underway after an initially difficult first day, and that the stated goal is a durable, permanent end to hostilities.
