United States Secretary of State John Kerry will travel to Kenya, Nigeria and Saudi Arabia next week for talks with senior government officials on regional issues, the State Department said on Thursday.
State Department spokesman John Kirby said the visit to Kenya would focus on South Sudan's peace process and Somalia's political transition.
In Nigeria, he would meet President Muhammadu Buhari to discuss cooperation on the fight against Boko Haram militants, the Nigerian economy and human rights issues, the spokesman said.
Boko Haram, the group responsible for the kidnapping of nearly 300 girls from a school in Chibok in 2014, has killed at least 20,000 people in its 7-year uprising against the Nigerian government. It surpassed Islamic State in 2014 to become the world's deadliest terrorist group, according to the 2015 Global Terrorism Index, published by the Institute for Economics and Peace.
