France summons US ambassador

French Foreign Minister Laurent Fabius has summoned the US ambassador over leaked documents that suggest her government spied on President Francois Hollande and two predecessors.

Diplomatic sources told AFP that US Ambassador Jane Hartley had been summoned for a meeting on Wednesday afternoon to discuss the documents published by Wikileaks the day before.

The documents - labelled Top Secret and appearing to reveal spying on Jacques Chirac, Nicolas Sarkozy and Hollande from 2006 to 2012 - were revealed online by WikiLeaks, in partnership with French newspaper Liberation and the Mediapart website.

The White House did not comment on past activity, but said it was not targeting Hollande's communications and will not do so in the future.
