Hundreds of thousands protest US troop presence in Iraq
Paris CNN  — 

Four aid workers from a French Christian charity have gone missing in Iraq and an investigation is underway to locate them, the organization said.

French non-governmental organization, SOS Chrétiens d’Orient (Christians of the Middle East), confirmed three French and one Iraqi national went missing in Baghdad on Monday.

The charity workers were conducting “administrative tasks,” including a visit to a new school opening, the NGO said in a statement on Friday.

The charity said there have been no ransom demands so far, and that French and Iraqi authorities are currently coordinating an investigation to find them.

“They disappeared between two meetings. They were on a mission authorized by the French Embassy,” Jeanne der Agopian, spokesperson for SOS Chrétiens d’Orient, told CNN.

According to the agency, the employees were expected to drive to an appointment on Monday afternoon.

After several unsuccessful attempts to contact the aid workers on Tuesday, SOS Chrétiens d’Orient alerted the French authorities on Wednesday.

SOS Chrétiens d’Orient’s mission is to help Christians in the region. The organization added the missing had a “thorough knowledge of the crisis areas” and “followed a security protocol adapted for the region.”

In December, a French journalist was kidnapped close to the U.S. embassy in Baghdad but was released 24 hours later.
