Reporters asked whether the U.N. would be represented at a Geneva signing ceremony for an Iran agreement, whether it would join a Strait of Hormuz monitoring mission, and about visa issues; the U.N. spokesperson said the organization had not seen the text of the agreement, would check mission details, and urged host‑country compliance on U.N. visas.

An unidentified speaker said the U.N. secretary-general is "following the situation with deep concern," appealed to national stakeholders in Guinea-Bissau to "exercise restraint and respect the rule of law," and said the secretary-general will continue to monitor developments.
