LONDON, April 4 (Reuters) - International law enforcement agencies have seized a dark web marketplace popular with cybercriminals, according to a notice posted to the site on Tuesday. A banner plastered across Genesis Market's site said domains belonging to the organization had been seized by the FBI. Britain's National Crime Agency - whose logo was also on the site - confirmed it was "participating in an international law enforcement operation targeting cyber criminals" but said it would not offer any further comment ahead of an announcement planned for Tuesday. Reuters could not immediately locate contact details for the Genesis Market's administrators.
