Colombia says it may extradite members of a Denmark-based group for donating $8,500 to the Revolutionary Armed Forces of Colombia, or FARC, the largest rebel group in the country.

Colombian Foreign Minister Carolina Barco said on Sunday she will seek information from authorities in the Nordic country about the donation by the group she referred to in Spanish as "The Rebellion Association."

Colombia's attorney general said international treaties allow for the extradition of those who collaborate with terrorists. The FARC is on the European Union's list of terrorist organizations.

"Those who give financial support to the FARC automatically become participants in the its crimes," Attorney General Luis Camilo Osorio said.

The FARC started 40 years ago as a peasant liberation movement. It has turned into a 17,000-strong army that the government says is more interested in kidnapping and exploiting Colombia's huge cocaine trade than in socialist ideology.

Its gunmen killed 34 peasants in a jungle hamlet in June after accusing them of picking coca leaf for outlaw right-wing paramilitaries, police said.

Poor Colombians pick coca, the raw material for cocaine, to sell to both rebels and paramilitaries, a dangerous trade which makes them targets.

Rebellion Association spokesperson Cristin Lungar told Colombian radio on Friday the contribution was made in protest of Denmark's new anti-terrorism laws.

Colombian government officials often express anger about what they say is romantic but ill-informed support that rebel groups enjoy in some leftist European circles, especially in Scandinavia.
