Parts of a national forest in California have been evacuated and closed down after a squirrel was found to be infected with the plague.

Los Angeles officials say visitors were ordered to leave the Angeles National Forest as a precaution after the rodent was trapped in a routine check.

Also known as the Black Death, the disease killed millions of Europeans in the Middle Ages.
