Madrid: At least 19 persons were arrested in Spain as part of an international operation against child pornography on Monday, officials said. The arrests were made for the possession and distribution of images which show abuse and sexual exploitation of minors, Xinhua news agency reported. The operation in Spain was launched when the American working group at the Cybercrime unit of Interpol alerted that Spanish internet users were exchanging files with images and videos of the sexual abuse of minors. The joint operation saw the arrest of 60 more people in Argentina, Brazil, Chile, Colombia, Costa Rica, the US, Guatemala, Mexico, Panama, Paraguay, the Dominican Republic, Uruguay and Venezuela, with over 200 searches carried out in 47 cities. Investigators were now analysing several files in order to try and identify the victims, many of whom could still be suffering from abuse. The Spanish Civil Guard confirmed that 14 minors in Spain and two in Colombia have already been identified as a result of the operation. Many of the victims were first contacted through a "well-known" social networking site.
