Here is more on our subject of how children are spending their summer (at least in the Northern hemisphere).
ABC reporters are in Gaza. They saw first-hand an Israeli shelling of a beach where four boys were playing. Their Report here.
The story is confirmed in this eyewitness account of Guardian reporter, Peter Beaumont.
"It was there that the second shell hit the beach, those firing apparently adjusting their fire to target the fleeing survivors. As it exploded, journalists standing by the terrace wall shouted: "They are only children."
"In the space of 40 seconds, four boys who had been playing hide and seek among fishermen's shacks on the wall were dead. They were aged between seven and 11; two were named Mohammad, one Zakaria and the youngest Ahed. All were members of the extended Bakr family."
UPDATE: You may remember New York Times photographer Tyler Hicks from various mideast wars. He has this account in Thursday's paper of the killing of the four Palestnian boys. His photos show the grusome condition of their blown-apart bodies. Here.
