Shane Bauer, 27, Sarah Shourd, 31, and Josh Fattal, 27, all graduates of UC Berkeley, have been held in Iran since July 30, after apparently straying into the country while hiking in northern Iraq's Kurdistan region.
The mothers of three Americans jailed for nearly nine months by the Iranian government say Swiss diplomats who visited them report two of the three are in poor health.
The diplomats learned that Shourd is suffering from a gynecological condition and battling depression, while Bauer has a stomach ailment. Their mothers weren't given details. The three also are considering a hunger strike.
"I'm really alarmed," said Nora Shourd, who lives in Oakland, Calif. "I'm alarmed for Sarah's health. I think she needs immediate care."
The Obama Administration on Friday stepped up its call for the release of the three. Officials also urged the Iranain government to issue visas to the hikers' families so they can visit them.
The three University of California at Berkeley graduates were detained July 31, after apparently straying into Iran while hiking in a scenic part of Iraq. This month, Iran's intelligence minister accused them of having links to U.S. intelligence services, which their families said was absurd.
The families maintain the trio was just out to have a fun vacation when they accidentally crossed the border.
