Sixteen American citizens and one Canadian, members of the Christian Aid Ministries, were abducted in Haiti on Saturday.
According to the announcement of this organization, the group included five men, seven women and five children.
The members of the mission disappeared in the suburbs of the capital Port-au-Prince, while they were going to visit an orphanage.
Earlier, Haitian security sources said an armed gang operating in the area between the Haitian capital and the border with the Dominican Republic was responsible for the abduction. It was not immediately clear if ransom was demanded for the release of the members of the mission.
