Snowden row casts shadow on Kerry's visit to Latin America
Secretary of State's visit to Latin America may be hit by fallout from Snowden's surveillance leaks

US Secretary of State John Kerry's attempts to build warmer relations with two US allies in Latin America may be hindered by reports of an American spy programme that widely targeted data in e-mails and telephone calls across the region.
Kerry is visiting Brazil and Colombia this week, his first trip to South America as the Obama administration's chief diplomat.
It comes at a time that disclosures by the National Security Agency whistle-blower Edward Snowden could chill talks on several fronts.
Those include trade and energy, and discussions about the October 23 state dinner that President Barack Obama is hosting for Brazil's president, Dilma Rousseff.
Kerry arrived late on Sunday in Bogota, the Colombian capital.
