PORT-AU-PRINCE, Haiti (AP) — The fate of an American nurse and her daughter kidnapped in Haiti last week remains unknown as the State Department refused to say whether the abductors made demands. Hundreds of Haitians marched in the capital Monday to protest an abduction that’s another example of the worsening gang violence that has overtaken much of Port-au-Prince. Alix Dorsainvil was working for El Roi Haiti, a nonprofit Christian ministry, when she and her daughter were seized by gunmen who burst into the clinic. Some community members said the abductors asked for ransom. The State Department on the day of her disappearance advised Americans to avoid travel in Haiti due to the growing security concerns.
