Iran's semi-official ISNA news agency says that authorities have released a British-Iranian woman on bail.

The Sunday report quotes Sousan Moshtaghian, mother of Ghoncheh Ghavami, as saying a judge Sunday released her daughter on nearly $30,000 bail.

Ghavami was detained in June after trying to attend a men's volleyball match between Iran and Italy, in defiance of a push by hardliners to enact full gender segregation.

The mother said Ghavami will be free until an appeals court rules on her case. She confirmed that an initial ruling had sentenced Ghavami to a year in prison for "propagating against the ruling system."

She said the family plans to hire a new lawyer for the appeal.

The judiciary has said her case is linked to opposition work, not a volleyball match.
