The case of the prominent Italian journalist detained in Iran is a test for Italy’s government as it gets caught up in Iran’s shadow war with the U.S.

Iran's state media say an Italian journalist has been arrested on charges of violating the Islamic Republic's laws.

Italian journalist Cecilia Sala has been detained in Tehran, Italy’s foreign ministry said in a statement Friday. She was in Iran on a reporting trip.

Italy is working “tirelessly” to bring home a journalist who has been under arrest in Iran for more than a week, the country said on Friday.

Iran warned Italy on Friday that it risked harming good bilateral relations if it bows to the "political and hostile goals" of the United States by detaining an Iranian engineer on a U.S. warrant in connection with a drone attack in Jordan last year that killed three American troops.

The fate of an Italian journalist detained in Tehran and an Iranian engineer imprisoned in Italy on a U.S. warrant grew even more intertwined Friday as the Iranian awaits possible extradition to the United States to face charges he provided drone technology to Iran's elite Revolutionary Guard corps.
