LONDON — US Secretary of State John Kerry kicked off his first official overseas trip by meeting Monday with British leaders in London, the first leg of a hectic nine-country dash through Europe and the Middle East. Kerry's first diplomatic meeting abroad came with British Prime Minister David Cameron, where they discussed the prospects of a free trade agreement between the United States and the European Union and the importance of the Middle East peace process. Cameron's spokesman, Jean-Christophe Gray, said the prime minister and Kerry also “reiterated their shared determination to prevent a nuclear-armed Iran" ahead of talks between world leaders and Tehran in Almaty, Kazakhstan, this week. The two also spoke about the challenges posed by fragile states such as Syria, Libya and Egypt, the spokesman added.— AP
