U.S. Secretary of State John Kerry is in London following two days of tense negotiations in Geneva that led the United States and five other nations to an agreement with Iran over its nuclear program.

Kerry landed in London on Sunday for talks with British Foreign Secretary William Hague and Libyan Prime Minister Ali Zidan.

The State Department says Kerry will talk to the two about Iran, Syria, peace talks between Israel and the Palestinians and worsening violence in Libya since the fall of longtime dictator Moammar Gadhafi in 2011.
