The first projectile hit the sea wall of Gaza City's little harbour just after four o'clock. As the smoke from the explosion thinned, four figures could be seen running, ragged silhouettes, legs pumping furiously along the wall. Even from a distance of 200 metres, it was obvious that three of them were children.
Jumping off the harbour wall, they turned on to the beach, attempting to cross the short distance to the safety of the Al-Deira hotel, base for many of the journalists covering the Gaza conflict.
They waved and shouted at the watching journalists as they passed a little collection of brightly coloured beach tents, used by bathers in peacetime.
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.
