Gaza, Alray  - Pink Floyd's Roger Waters asked  musicians to boycott Israel, in an open letter to his Facebook page and the Palestinian activists website Electronic Intifada.

"I write to you now, my brothers and sisters in the family of Rock and Roll, to ask you to join with me, and thousands of other artists around the world, to declare a cultural boycott on Israel," he wrote.

"Please join me and all our brothers and sisters in global civil society in proclaiming our rejection of Apartheid in Israel and occupied Palestine, by pledging not to perform or exhibit in Israel or accept any award or funding from any institution linked to the government of Israel, until such time as Israel complies with international law and universal principles of human rights," he wrote in his letter.

Waters has been a frequent advocate of the Boycott, Divestment, Sanctions movement regarding Israel, encouraging institutions to withdraw investments there, among other tactics.
