Obama: US journalist jailed in Iran was not a spy

US President Barack Obama on Sunday said he's "gravely concerned" about the safety and well-being of a US journalist jailed in Iran and stressed that he's confident she is not involved in espionage against Teheran. At the Summit of the Americas, Obama said he's working to ensure the safety of Roxana Saberi, a 31-year-old dual American-Iranian citizen. She was sentenced to eight years in an Iranian prison on charges of spying for the United States. Saberi's case has been an irritant in US-Iran relations at a time when Obama is offering to start a dialogue.
