Actor George Clooney is urging consumers to boycott nine hotels linked to the country of Brunei over its plans to impose harsh new criminal sentences.

The penalties being implemented, based on Islamic law, include death by stoning for gays and amputation for theft.

Clooney admitted he's stayed in some of the luxury hotels owned by the Brunei Investment Agency, saying he "hadn't done his homework."

Amnesty International has condemned Brunei's new penal code as "cruel and inhuman."

Actor George Clooney is calling for a boycott of nine luxury hotels owned by the Brunei Investment Agency over Brunei's plans to implement Islamic criminal laws, such death by stoning for gay sex.

In an opinion piece in Deadline.com, Clooney said a boycott is necessary to keep money from flowing "directly into the pockets of men who choose to stone and whip to death their own citizens for being gay or accused of adultery." Among the nine hotels owned by the Brunei Investment Agency, which is owned by the Brunei government, are U.S. hotels The Beverly Hills Hotel and the Hotel Bel-Air.

Clooney noted that he's stayed at many of the hotels owned by Brunei, a small nation located on the island of Borneo, but said he was unaware of their ownership "because I hadn't done my homework." He acknowledged that a boycott is unlikely to change Brunei's laws, but said consumers must decide whether they want their money to support laws that violate human rights.

On Wednesday, Amnesty International slammed Brunei's plans to implement what the rights group called "vicious" laws," which also apply to children. The new penalties take effect April 3.
