Secretary of State John Kerry is commemorating victims of Kenya's past and present terror attacks and offering U.S. support in the fight against al-Shabaab.

His trip to the African country coincides with improving U.S.-Kenyan ties and sets the stage for President Barack Obama's visit this summer.

Kerry laid a wreath for the victims of the deadly 1998 bombing of the U.S. Embassy to Kenya and offered condolences to families and friends of the 148 people, mainly students, massacred at a Kenyan university last month.

He then met Kenyan President Uhuru Kenyatta.

U.S. relations with Kenyatta have improved since the International Criminal Court dropped charges of crimes against humanity against him in December. Those were linked to violence that killed hundreds of people after Kenya's contested 2007 presidential election.
