Security breach at Tower of London, Crown Jewels safe

LONDON (AP) - A rare security breach has been reported at the Tower of London, one of the British capital's most famous landmarks.

Authorities say the Crown Jewels and other unique artefacts are safe, but locks had to be changed after an intruder broke in and stole some keys.

Officials said on Monday that the keys were stolen from a sentry box at the site. They would have provided access to the Tower's drawbridges and some other areas.

Authorities say the keys were stolen last Tuesday and a police investigation into the theft is under way.
