The US surveillance forces, tasked with identifying targets for drone strikes, allegedly used software which monitored private communications, including phone calls and wifi traffic, the media specified.

The ICO pledged to investigate the complaint but noted that it was important to look into the applicability of the UK law to foreign bases operating in the United Kingdom.
The base at Menwith Hill is the US largest eavesdropping center with about 2,500 employees. The center provides real-time surveillance for the US military operations and remotely controls weapons for the US forces in their interventions worldwide.
