LONDON - The United States monitored the phone conversations of 35 world leaders according to classified documents leaked by fugitive whistleblower Edward Snowden, Britain's Guardian
newspaper said on Thursday.
Phone numbers were passed on to the US National Security Agency (NSA) by an official in another government department, according to the documents, the Guardian
said on its website.
It added that staff in the White House, State Department and the Pentagon were urged to share the contact details of foreign politicians.
The revelations come after Germany demanded answers from Washington over allegations Chancellor Angela Merkel's phone was bugged, the worst spat between the two countries in a decade.
