The lawyer for jailed Iranian-American journalist Roxana Saberi says an Iranian court will hear the appeal against her jail sentence on Sunday.
Lawyer Abdolsamad Khorramshahi made the announcement Saturday.
It is not clear how long it will take the court to render a verdict in the case of Saberi, who was sentenced to eight years in prison last month on espionage charges.
Her family and the U.S. government say the charges against her are baseless.
Saberi's father, Reza Saberi, says the 32-year-old freelance journalist ended a hunger strike Monday after refusing to eat for nearly two weeks.
Iran has criticized international involvement in the case, saying the judiciary is independent and outside interference contradicts international norms.
