(AP) -- The British Foreign Office said Johnson would meet with Iranian Foreign Minister Mohammed Javad Zarif on Saturday to discuss "a number of consular cases involving dual nationals," along with other bilateral issues.

Johnson is in Tehran as part of a three-nation Persian Gulf tour, which the Foreign Office said was focused on the Iran nuclear deal and "how to bring an end to the conflict in Yemen."

Efforts to free Nazanin Zaghari-Ratcliffe, are believed to top Johnson's agenda.

The state-run IRNA news agency said Johnson would meet Iranian President Hassan Rouhani and other top officials during his two-day visit.
