ROME (AP) — An Italian journalist detained in Iran since Dec. 19 and whose fate became intertwined with that of an Iranian engineer wanted by the United States was freed Wednesday and is heading home, Italian officials announced.

A plane carrying Cecilia Sala took off from Tehran after “intensive work on diplomatic and intelligence channels,” Premier Giorgia Meloni’s office said, adding that Meloni had informed Sala's parents of the news.

There was no immediate word from the Iranian government on the journalist’s release.

Sala, a 29-year-old reporter for the Il Foglio daily, was detained in Tehran on Dec. 19, three days after she arrived on a journalist visa. She was accused of violating the laws of the Islamic Republic, the official IRNA news agency said.

Italian commentators had speculated that Iran was holding Sala as a bargaining chip to ensure the release of Mohammad Abedini, who was arrested at Milan’s Malpensa airport three days before on Dec. 16, on a U.S. warrant.

The U.S. Justice Department accused him and another Iranian of supplying the drone technology to Iran that was used in a January 2024 attack on a U.S. outpost in Jordan that killed three American troops.

He remains in detention in Italy.
