Costa Rican authorities say Nicaraguan Contra leader Eden Pastora has become an international suspect on charges he violated environmental laws when he led a dredging project in a river between the two Central American nations.

Vice Minister of Security Celso Gamboa says Interpol included Pastora on its list of fugitives Tuesday.

Pastora served as president of a committee for development of the San Juan River that is at the center of a lengthy dispute between the neighboring countries.

The Costa Rican government says the 76-year-old Pastora made illicit use of public property during the 2010 dredging project in which he meant to recover water lost after Costa Rica rerouted the river in the 1940s.
