Spain’s deputy prime minister says a Spanish aid worker kidnapped late last year in Mauritania by suspected Islamic militants has been freed, but two colleagues remain in captivity.

Maria Teresa Fernandez de la Vega says Alicia Gamez was released on Wednesday and is now on a plane to Barcelona.

She says she had spoken to Ms. Gamez, and she is “safe and sound.”

Ms. Gamez and two male colleagues from an aid group called Barcelona Accion Solidaria were kidnapped by gunmen on November 29 while delivering relief material to poor villages in Mauritania. Al—Qaeda’s North African offshoot claimed responsibility.
