A Spanish judge has accused Venezuela of collaborating with Basque separatists and Colombian rebels, and says these two groups plotted to assassinate Colombia's president.

Judge Eloy Velasco made the allegation Monday in a 26-page indictment in which he charged six members of the Basque group ETA, most of them exiled in Latin America, and seven members of the Colombian leftist rebel group FARC with a variety of crimes including terrorism and conspiracy to commit murder.
