Israeli air strikes have hit Al Ahli hospital in Gaza. More than 500 people - patients, doctors & those sheltering - have been killed. What unspeakable horror. We will mourn their loss forever. Our leaders could have spoken up for peace. They chose to cheer on war instead. When will they demand an end to these atrocious war crimes? How many Palestinian lives will it take to call for these indiscriminate killings to stop? Please, for the sake of humanity, raise your voice for an immediate ceasefire. The existence of the Palestinian people is at stake.
