The website of Britain's Royal Navy has been closed after hackers gained unauthorized access to the military site.

Military computer specialists are investigating the cyber-security breach.

A statement posted on the website Monday said it is closed for "essential maintenance."

The navy said in a statement that the website was compromised over the weekend but no damage was done.

The site has been taken down temporarily as a precaution.

A hacker who goes by the name TinKode has claimed to have gained access to the sensitive site.

The navy said the unauthorized access gained to the "public relations" website did not compromise sensitive information.
