No personnel, aircraft or infrastructure affected, spokesperson says

A spokesperson for U.S. European Command said security forces at Royal Air Force Base Lakenheath in eastern England have responded to unauthorized drone activity, and that the U.S. military is taking “all measures” to keep base installations, aircraft and service members safe.

The spokesperson, who spoke on condition of anonymity to discuss sensitive military matters, added that no personnel, aircraft or infrastructure have been affected by the activity.

Unauthorized drone activity prompted a security response at the American base in Britain, the U.S. military said Friday. Lakenheath is in eastern England.

The response comes just days after the U.S. moved more than a dozen aircraft from a different base in eastern England because of a threat.
