Abducted Colombian girl Nohora Valentina Munoz released

A 10-year-old Colombian girl whose kidnapping last month shocked the nation has been released.

As Nohora Valentina Munoz and her father were reunited, Jorge Enrique Munoz spoke of his relief at her release.

It is not yet clear who kidnapped her as she walked to school in the town of Fortul near Colombia's border with Venezuela.

But suspicion had fallen on left-wing rebel groups active in the region.

Thousands of troops and police were involved in the efforts to rescue her.
