Sisters Khloe and Kim Kardashian

Days after a flour bomb attack on reality TV star Kim Kardashian, her sister Khloe has quit Peta amid claims that her sister's attacker had links with the animal rights organisation.

Khloe, 27, who posed naked for the charity for its I'd Rather Go Naked Than Wear Fur campaign in 2008, confirmed on her blog that she was severing her ties with the organisation.

"Not only has Peta lied to the public, but they have proved that they support this kind of behaviour," she blogged.

"I've been a vocal supporter of Peta for a long time but I have also been very vocal about anti-bullying, so this was a huge disappointment for me.

"I don't wear fur but that doesn't mean I am going to force my views on anyone else, especially by violating them," she said. "Bullying and harassment is never a solution and I won't be a part of any organisation that thinks otherwise."

Peta denied responsibility for the stunt but admitted it intended maximising exposure from the incident.

Kim, 31, was pelted with flour at the launch of her new fragrance at the London Hotel in West Hollywood, California.

The assailant, who was not named but was believed to be a long-time member of Peta, called Kim a "fur hag" in the attack. She was arrested.

Khloe tweeted fans: "I wish I was with my sister tonight. I bet you that woman wouldn't have dared tried a thing.

"I'm proud of how Kim handled the situation."
