More than 200 writers in the United Kingdom, including Zadie Smith, Michael Rosen, Hanif Kureishi, and Elif Shafak, have signed an open letter urging a complete boycott of Israel. The letter calls for the boycott to remain until Gaza receives adequate food, water, and medical supplies, and until humanitarian relief is restored under the supervision of the United Nations. The writers express regret for the impact on individuals who oppose Israeli government policies but argue that previous efforts have failed to secure aid for Gaza. They also demand the return of all hostages, an end to violence, and emphasize their opposition to all forms of prejudice and hate.
