Israel's murder of four Palestinian children playing on a beach in Gaza City was witnessed by many bystanders, including journalists who have offered harrowing accounts, photos and video as they watched the terrified boys run for their lives. Killed were Ahed Atef Bakr, 10, Zakariya Ahed Bakr, 10, Mohammad Ramiz Bakr, 11, and Ismail Mahmoud Bakr, 9. Warning: Graphic. You can help send food, medical supplies and other humanitarian aid via Middle East Children's Alliance here. We know: It's not much. But it's something, not nothing, which feels untenable.
