In the wake of what French President Francois Hollande described as an 'unacceptable' security breach, Jane Hartley was summoned to the French Foreign Ministry, according to French diplomats who spoke on condition of anonymity because they were not authorised to be publicly named.

The disclosures, which emerged yesterday in French daily, mean that France has joined Germany on the list of US allies targeted by the National Security Agency.

The documents appear to capture officials in Paris talking candidly about Greece's economy and relations with Germany and about American espionage of its allies. While there were no huge surprises, the release angered and embarrassed French officialdom.

"This involves unacceptable acts that have already given rise to discussions between the United States and France," Hollande said in a statement after an Emergency Defense Council meeting.

The statement said France has reinforced protective measures after the document release, without elaborating. The release appeared to be timed to coincide with a vote in the French Parliament on a Bill allowing broad new surveillance powers, in particular to counter terrorist threats.

The Senate approved it yesterday and the lower house of Parliament is expected to give it final approval today. There was no instant confirmation of the accuracy of the documents, which covered intercepts from 2006-12 and WikiLeaks has a track record of publishing intelligence and diplomatic material.
