Aarab Marwan Barghouti, the son of jailed Palestinian official Marwan Barghouti who is leading a hunger strike of more than 1,500 Palestinians detained in Israeli prisons, gave a boost to prisoner solidarity campaigns by releasing a video of him drinking a bitter mixture of salt and water. The clip closes by asking others to participate in his “salt water challenge” in solidarity with the Palestinian hunger strikers.

Nearly 100 Israelis sign onto an open letter endorsing Palestinian prisoners on hunger strike, “We, a group of conscientious Israeli-Jews, would like to express our deep respect and solidarity with you – the 1,500 or more Palestinians who embarked on a collective open ended hunger strike to demand your basic rights.”
