Armed rebels have seized two scientists and their guide during ecological fieldwork in northern Colombia. The Revolutionary Armed Forces of Colombia (FARC) has claimed responsibility for the kidnappings.
FARC abducted ornithologist Diego Calderón and botanist Hermes Cuadros along with their guide José Saurith on 17 April during an expedition in a potential national park near the border with Venezuela.
Biologists have launched an international campaign demanding their release. They are targeting a FARC website with messages condemning the kidnappings and staging 'Birding for Freedom' events worldwide to put pressure on FARC to free the men.
