EU leaders have been giving their reaction to accusations to German and French accusations that the United States has been running spying operations in their countries.
Belgium Prime Minister Elio Di Rupo said: " We cannot accept this systematic spying, whatever it may be. We need to take European measures."
Swedish Prime Minister Fredrik Reinfeldt said surveillance should not be used to "listen to each other, when we look at elected leaders."
Finland's Prime Minister Jyrki Katainen said: "We have to get clarification of what has happened and we also need a guarantee that this will never happen again if it has happened."
"This is serious. I will support her (Merkel) completely in her complaint and say that this is not acceptable. I think we need all the facts on the table first", Dutch Prime Minister Mark Rutte said.
