George Clooney has called for a boycott of nine hotels connected to the ruler of Brunei, where gay sex will be punishable by death starting April 3.

In an op-ed written for Deadline Hollywood, Clooney spoke out against Brunei’s harsh law, which permits death by stoning for gay sex and adultery. Clooney writes the Sultan of Brunei owns “nine of the most exclusive hotels in the world,” and implores people to stop staying at the properties in protest.

Sharing that he has previously stayed at many of the hotels owned by the Sultan of Brunei because he did not know about their connection, Clooney wrote, “They’re nice hotels. The people who work there are kind and helpful and have no part in the ownership of these properties.”
