An online tool that claims to reveal the identity of organisations that edit Wikipedia (a free online encyclopaedia that can be updated by anyone) pages has revealed that the CIA (Central Intelligence Agency) was involved in editing entries.

The Wikipedia scanner allegedly shows that workers on the agency's computers made edits to the page of Iran's president.

The scanner also indicated that Vatican computers were used to remove content from a page about the leader of the Irish republican party Sinn Fein, Gerry Adams.
