Kerry will "travel to London on November 24" for talks with British Foreign Secretary William Hague and Libyan Prime Minister Ali Zeidan, Jen Psaki said today.
With the Libyan premier, Kerry will discuss the security situation and political reforms in the country, which has been roiled by strife since Moamer Kadhafi was overthrown in 2011.
Kerry arrived in Switzerland this morning along with other foreign ministers amid growing hopes for a landmark nuclear deal between six world powers and Iran.
Since their arrival however, officials have indicated that there are still differences preventing the signing of a deal limiting Iran's nuclear programme in exchange for sanctions relief.
Hague is also currently in Geneva along with foreign ministers from China, Russia, France and Germany.
News about Kerry's departure coincided with comments from Tehran's lead negotiator Abbas Araqchi that the talks were "difficult" and that Iran was not sure that a deal would be reached today.
