From A to B to CIA: How the spy network functions
Data is collected from “spy bases” in US embassies by a special CIA/NSA unit often located on the roof of the US embassy (circled above on top of the US embassy in Madrid). The operational nests in Europe and Central Asia are located in Athens, Baku, Budapest, Frankfurt, Geneva, Kiev, Madrid, Milan, Moscow, Paris, Prague, Pristina, Rome, Sarajevo, Tbilisi, Tirana, Vienna and Zagreb.

The data is then transmitted to the College Park joint CIA/NSA centre (pictured above) in Maryland for analysis and use by America’s intelligence agencies. Under Britain’s long-standing intelligence-sharing pact with the United States, material can also be transmitted to GCHQ via a high-security link installed during the 1990s. (Getty Images)
