BRUSSELS (Reuters) - German and French accusations that the United States has run spying operations in their countries are likely to dominate a meeting of EU leaders starting on Thursday.
Here are the reactions of EU leaders arriving in Brussels for the summit:
DUTCH PRIME MINISTER MARK RUTTE
"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.
"We have done research, also in Europe, into what data the NSA has or has not collected. Once we have these facts, we can take the next steps."
FINLAND'S PRIME MINISTER JYRKI KATAINEN
"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."
SWEDEN'S PRIME MINISTER FREDRIK REINFELDT
"Our capacity to search for this kind of information is to hinder terrorism, criminal activities, the risk of war. That should be clear.
"We are doing this, but it's actually to preserve the freedom, our openness in our societies. It should not be used to listen to each other, when we look at elected leaders."
AUSTRIA'S VICE CHANCELLOR MICHAEL SPINDELEGGER
"We will not accept that data from Austria is hoovered up and analyzed other than when there is a legal basis for doing so.
"It's clear that, in particular between countries that are on friendly terms, you can't simply listen in on people's conversations and hoover up and analyze data, other than when there is really a mutual basis for so doing.
"We Europeans should be self-confident in making this clear to the U.S. We must build up a relationship of trust with the U.S., which has been damaged."
