An EU summit is due to begin in Brussels with fresh allegations of US spying threatening to overshadow talks.
It comes a day after German Chancellor Angela Merkel called President Barack Obama over claims that the US had monitored her mobile phone.
France's President Francois Hollande is pressing for the issue to be put on the agenda following reports that millions of French calls had been monitored.

BBC Europe Editor Gavin Hewitt says some leaders are likely to want to use the summit to demand further clarification from Washington over the activities of its National Security Agency (NSA) in Europe.
The US is being called to account by its allies over allegations of spying based on material said to originate from fugitive American leaker Edward Snowden.
