“Chileans, sons of bitches, you’ve been hacked by a Peruvian,” the hacker said on the site www.anfp.cl.

An ANFP spokesman confirmed the hacking and said the site had briefly shut down after the cyber graffiti was discovered.

The hacker went by the initials The-RjR and also used the site to fuel an age-old rivalry between Chile and Peru about who invented ceviche, a dish of raw fish marinated in lime or lemon juice, and Pisco, a liquor produced from grapes.

Relations between Peru and Chile have improved markedly over recent years after being strained since a 19th century sea war, but debate is always heated over the origin of certain culinary delicacies.
