Another person has been arrested in the United Kingdom in connection with a planned attack on RAF Fairford airbase, AP reports.
A 22-year-old British citizen was detained on suspicion of preparing to carry out terrorist attacks in central London.
Earlier, six people accused of planning an attack on US bomber aircraft stationed at the airbase were arrested. They were released on bail pending the completion of the investigation.
The United States removed the bomber aircraft from the base due to the potential threat.
