Secret documents reveal more than 1,000 targets of American and British surveillance in recent years, including the office of an Israeli prime minister, heads of international aid organizations, foreign energy companies and a European Union official involved in antitrust battles with American technology businesses.

While the names of some political and diplomatic leaders have previously emerged as targets, the newly disclosed intelligence documents provide a much fuller portrait of the spies’ sweeping interests in more than 60 countries.

Britain’s Government Communications Headquarters, working closely with the National Security Agency, monitored the communications of senior European Union officials, foreign leaders including African heads of state and sometimes their family members, directors of United Nations and other relief programs, and officials overseeing oil and finance ministries, according to the documents. In addition to Israel, some targets involved close allies like France and Germany, where tensions have already erupted over recent revelations about spying by the N.S.A.

Details of the surveillance are described in documents from the N.S.A. and Britain’s eavesdropping agency, known as GCHQ, dating from 2008 to 2011. The target lists appear in a set of GCHQ reports that sometimes identify which agency requested the surveillance, but more often do not. The documents were leaked by the former N.S.A. contractor Edward J. Snowden and shared by The New York Times, The Guardian and Der Spiegel.
