An Italian journalist detained in Iran since December 19 and whose fate became intertwined with that of an Iranian engineer wanted by the United States has been freed and is heading home, officials announced.

Italian journalist Cecilia Sala was freed from an Iranian prison Wednesday and was flying home, Italian Prime Minister Giorgia Meloni’s office said. Her release came three weeks after she was detained in Tehran while working on a journalist visa. Iran had accused Sala of “violating the law of the Islamic Republic of Iran.”

Italy has summoned Iran’s ambassador to demand the immediate release of an Italian journalist detained in Tehran.

An Italian journalist detained in Iran last month has been freed and is on a flight back to Rome, the Italian government says. Cecilia Sala, 29, was arrested on 19 December, three days after an Iranian engineer was detained by Italian authorities in Milan on suspicion of supplying drone technology that led to the deaths of US soldiers.
