Three French aid workers are missing in eastern Yemen, and security officials say they fear they were abducted by tribesmen.
Kidnappings are common in Yemen, where tribesmen use abductions to try to force concessions from the government, such as the release of fellow tribesmen in prison.
The two women and one man work for Triangle Generation Humanitaire, based in Lyon, France. One of the organization's directors, Patrick Verbruggen, says they work in the eastern town of Sayoun and disappeared Saturday.
French Foreign Ministry spokesman Bernard Valero says it is too soon to confirm a kidnapping.
Yemeni security officials say a woman at their compound reported them missing. They spoke on condition of anonymity because they are not authorized to speak to journalists.
