Wife Of Javier Espinosa, Kidnapped Journalist, To Captors: 'Set Them Free'

Monica García Prieto, the wife of Javier Espinosa, a journalist being held captive in Syria, is pleading for the release of her husband and his colleague, Ricardo García Vilanova.

Espinosa, a correspondent for El Mundo newspaper, and Vilanova, a freelance photographer, disappeared in Syria in September. A militant group, Islamic State of Iraq and al-Sham, is suspected of kidnapping them, El Mundo said.

Prieto, a Middle East correspondent based in Beirut, issued a public plea to their captors in a video posted Wednesday. She said that Espinosa and Vilanova have risked their lives in order to raise people's awareness of the civil war in Syria and pose no danger to the captors. "Please, honor the revolution they protected, and set them free,” she implored.

The Free Javier and Ricardo Campaign, which Prieto launched earlier this week, features footage of their reports from Syria and of Espinosa and Vilanova working on the ground.

Syria has been notoriously dangerous ground for journalists, with the Committee To Protect Journalists estimating in November that at least 30 are being held captive.
