Inside Menwith Hill

The narrow roads are quiet and winding, surrounded by rolling green fields and few visible signs of life beyond the occasional herd of sheep. But on the horizon, massive white golf ball-like domes protrude from the earth, protected behind a perimeter fence that is topped with piercing razor wire. Here, in the heart of the tranquil English countryside, is the National Security Agency’s largest overseas spying base.

Once known only by the code name Field Station 8613, the secret base — now called Menwith Hill Station — is located about nine miles west of the small town of Harrogate in North Yorkshire. Originally used to monitor Soviet communications through the Cold War, its focus has since dramatically shifted, and today it is a vital part of the NSA’s sprawling global surveillance network.

For years, journalists and researchers have speculated about what really goes on inside Menwith Hill, while human rights groups and some politicians have campaigned for more transparency about its activities. Yet the British government has steadfastly refused to comment, citing a longstanding policy not to discuss matters related to national security.

Now, however, top-secret documents obtained by The Intercept offer an unprecedented glimpse behind Menwith Hill’s razor wire fence. The files reveal for the first time how the NSA has used the British base to aid “a significant number of capture-kill operations” across the Middle East and North Africa, fueled by powerful eavesdropping technology that can harvest data from more than 300 million emails and phone calls a day.

Over the past decade, the documents show, the NSA has pioneered groundbreaking new spying programs at Menwith Hill to pinpoint the locations of suspected terrorists accessing the internet in remote parts of the world. The programs — with names such as GHOSTHUNTER and GHOSTWOLF — have provided support for conventional British and American military operations in Iraq and Afghanistan. But they have also aided covert missions in countries where the U.S. has not declared war. NSA employees at Menwith Hill have collaborated on a project to help “eliminate” terrorism targets in Yemen, for example, where the U.S. has waged a controversial drone bombing campaign that has resulted in dozens of civilian deaths.

The disclosures about Menwith Hill raise new questions about the extent of British complicity in U.S. drone strikes and other so-called targeted killing missions, which may in some cases have violated international laws or constituted war crimes. Successive U.K. governments have publicly stated that all activities at the base are carried out with the “full knowledge and consent” of British officials.

The revelations are “yet another example of the unacceptable level of secrecy that surrounds U.K. involvement in the U.S. ‘targeted killing’ program,” Kat Craig, legal director of London-based human rights group Reprieve, told The Intercept.

“It is now imperative that the prime minister comes clean about U.K. involvement in targeted killing,” Craig said, “to ensure that British personnel and resources are not implicated in illegal and immoral activities.”

Objective Peckham

As he walked through the busy streets of London, Bilal el-Berjawi was glancing over his shoulder. Everywhere he went, he suspected he was being followed. Within a few years — 4,000 miles away in remote Somalia — he would be dead, killed by a secret U.S. drone strike.

A small and stocky British-Lebanese citizen with a head of thick dark hair, Berjawi had grown up much like any other young boy in the United Kingdom’s capital city, attending school during the day and playing soccer with friends in his free time. But by his early 20s he was leading no ordinary life. He was suspected of having cultivated ties with senior al Qaeda militants in East Africa, his British citizenship was abruptly revoked, and he was placed on a U.S. kill list.

In January 2012, Berjawi met his sudden end, about 10 miles northwest of Mogadishu, when a missile crashed into his white car and blasted it beyond recognition.

At the time of Berjawi’s death, the Associated Press reported that the missile strike targeting him had been carried out by a drone, citing an anonymous U.S. official. The Economist criticized the secrecy surrounding the attack and questioned whether it had amounted to a “very British execution.”

Now, a classified U.S. document obtained by The Intercept shines new light on the circumstances surrounding Berjawi’s death. It reveals that the U.S. government was monitoring him for at least five years as he traveled between London and Somalia; that he was targeted by a covert special operations unit running a fleet of more than two dozen drones, fighter jets, and other aircraft out of East Africa; and that cellphone surveillance facilitated the strike that killed him.

The document, a case study included in a secret 2013 report by the Pentagon’s Intelligence, Surveillance, and Reconnaissance Task Force, does not mention Berjawi by name, instead referring to a target code-named “Objective Peckham.” But it contains enough specific details about the target’s movements and the time and place of the attack that killed him to confirm his identity beyond doubt.

The Intercept has pieced together the final years of Berjawi’s life based on the Pentagon case study, public records, interviews with individuals who knew him, and a transcript of a long conversation Berjawi had in April 2009 with members of Cage, a London-based rights group, in which he discussed his encounters with security agencies in the U.K. and Kenya.

The story of Berjawi’s life and death raises new questions about the British government’s role in the targeted assassination of its own citizens — also providing unique insight into covert U.S. military actions in the Horn of Africa and their impact on al Qaeda and its affiliate in the region, al Shabaab.
