The ex-husband of former guerrilla-held hostage Ingrid Betancourt is France's new ambassador to Costa Rica.
Fabrice Delloye campaigned for his ex-wife's release during the six years she was held by the Revolutionary Armed Forces of Colombia, or FARC.
A dual French-Colombian citizen, Betancourt was running for Colombia's presidency when she was captured. She was freed in July when military agents posing as aid workers helicoptered 15 hostages to freedom without a shot being fired.
Delloye and Betancourt were married from 1981 to 1990 and have two children.
Delloye presented his credentials to Costa Rica's government Thursday. He has held diplomatic posts in Colombia, Ecuador, the Dominican Republic and Canada.
