More than 150 literary figures, including nine Pulitzer Prize winners, are calling for Israel to free an Israeli-Arab poet charged with inciting violence through social media.

The open letter announced Tuesday in support of Dareen Tatour, who has been under house arrest since October, was organized by Jewish Voice for Peace and Adalah-NY (The New York Campaign for the Boycott of Israel). Authors Alice Walker, Claudia Rankine and Dave Eggers were among those who signed on in asserting “poetry is not a crime.”
