(bbc) French-Colombian politician Ingrid Betancourt and 14 other hostages held by rebels in Colombia have been rescued by government troops. Ms Betancourt had been held for more than six years by the rebel Farc group and was their highest-profile captive. French President Nicolas Sarkozy, who had made her rescue a priority, said he was very happy. Her children, who spoke of their joy, are to fly to meet her. The Farc has been fighting to overthrow the Colombian government for 40 years. Wearing military fatigues, a pale Ms Betancourt smiled as she emerged with other hostages from a military plane in the Colombian capital Bogota to be greeted by her mother and husband.
