Samsung is under attack from an animal rights organisation accused of cruelty to sheep in its "extreme sheep LED art" video viral advert.

PETA has written to the president and chief executive of Samsung in Europe, In-Soo Kim, apparently urging him to pull the ad.

The viral - a previous Pocket-lint "video of the day" - depicts sheep being herded around with LED lights strapped to their backs.

PETA's letter read: "They [sheep] are sentient, intelligent and complex animals… Tormenting, harassing and scaring sheep to promote a product is unacceptable".

We're just wondering how the letter will read when PETA spies Samsung's recent phone ad, that uses no less that 38 cute, fluffy animals to promote their latest handset.
