(CNN) -- Iranian customs agents arrested a 55-year-old American woman accused of spying, local Iranian media outlets reported on Thursday.

In July 2009, three Americans were detained in Iran for spying after they allegedly strayed across an unmarked border while hiking in Iraq's Kurdistan.
One of them, Sarah Shourd, was released from an Iranian prison last September on humanitarian grounds.
Those still in prison are Josh Fattal and Shane Bauer.
Two German journalists, identified only as a reporter and photojournalist, were arrested in Iran in October and charged with espionage after they interviewed the son and lawyer of Sakineh Mohammadi Ashtiani, who was convicted of adultery in 2006 and sentenced to death by stoning. CNN
