NSA spying: France summons US envoy after Wikileaks revelation

France has summoned the US envoy in Paris over claims that the US spied on President Francois Hollande and his two predecessors, officials say.

Whistleblower website Wikileaks reports the US National Security Agency (NSA) spied on Mr Hollande, Nicolas Sarkozy and Jacques Chirac between 2006-12.

Mr Hollande called an emergency meeting and said France would "not tolerate" acts that threaten its security.
