NATO is condemning the release by Wikileaks of diplomatic cables detailing the deployment of US tactical nuclear weapons in Europe.
NATO spokeswoman Oana Lungescu on Tuesday described the leaks as "illegal and dangerous."
Leaked US diplomatic cables show that most of about 200 US tactical nuclear bombs still left in Europe are based in Belgium, the Netherlands, Germany and Turkey. The four nations have been long suspected of hosting the warheads, but NATO and the governments involved have always refused to confirm this.
The B-61 bombs, America's oldest nuclear weapons, date back to the 1950s. They were part of Washington's effort to demonstrate a commitment to NATO's defense during the Cold War by embedding such weapons near potential battlefields.
