Two individuals were arrested Thursday after attempting to enter HM Naval Base Clyde in Scotland, which houses the United Kingdom's nuclear-armed submarines.

The arrested individuals include a 34-year-old man and a 31-year-old woman, according to authorities. The attempted entry was unsuccessful.

HM Naval Base Clyde, also known as Faslane, serves as the home port for the Royal Navy's nuclear submarine fleet. The facility is located on the west coast of Scotland and is considered one of the UK's most sensitive military installations.

Authorities have not released additional details about the circumstances of the attempted entry or the identities of those arrested. The incident remains under investigation.
