The mothers of three US hikers detained for 10 months in Iran called for their release as a "humanitarian gesture" after an emotional reunion with their children, an AFP correspondent said.

The mothers of three UC Berkeley graduates being held in Iran are marking 11 months of their captivity with a letter to the country's supreme leader pleading for their release.
The letter sent Wednesday to Ayatollah Ali Khamenei is signed by the mothers of Shane Bauer, Sarah Shourd and Josh Fattal. Iranian officials have accused the three of espionage after they were taken into captivity along the Iran-Iraq border last July during what their families say was a hiking trip.
Cindy Hickey, Nora Shourd and Laura Fattal appealed to Khamenei to "bring the cruel injustice of their continued detention to an end." The mothers say their children should either be tried immediately or released.
The mothers unsuccessfully sought a meeting with Khamenei when they traveled to Iran last month.
