The United States National Security Agency reportedly bugged the United Nations’ New York Headquarters according to Germany’s weekly news magazine Der Spiegel, Euronews reports.

In the article released on Sunday it said experts from the NSA cracked the U.N. video conferencing system in the summer of 2012.

U.S. documents obtained by fugitive former intelligence contractor Edward Snowden state how the European Union and the United Nations Vienna-based watchdog, the International Atomic Energy Agency were also targeted.

The report in Der Spiegel also told how the United States had a surveillance programme in 80 of its embassies and consulates around the world.

Washington has said its spies operate within the law and that the leaks have damaged national security.
