Authorities in New York say 12 members of a Colombian organization are charged with conspiring to aid a foreign terrorist group and taking a U.S. citizen hostage.

Prosecutors said Monday that only two of the defendants are in custody. The rest are fugitives.

An indictment unsealed in Manhattan accuses the defendants of aiding a group designated by the U.S. government as a terrorist organization.

It says the group kidnapped a U.S. citizen in April 2008. The victim was released in February after the family paid ransom.

The U.S. attorney said in a statement that the charges are an important step to fight terrorism carried out by international drug dealers.
