Hollande and Obama speak over US spying allegations

French President Francois Hollande says he spoke with President Barack Obama amid claims of US eavesdropping on French leaders, and that Obama reiterated promises to stop spying tactics considered "unacceptable between allies".

Hollande said in a statement on Wednesday that the two spoke by telephone after the release of WikiLeaks documents about NSA intercepts of conversations involving Hollande and his two predecessors between 2006 and 2012.

President Obama made a similar pledge after Edward Snowden revealed the extent of NSA surveillance powers in 2013.
