Israel massacred 7 people in a Gaza Beach recently including 3 children and injuring 30 Palestinians most of them lying unconscious from the heavy shelling.
On this occasion, the Israelis, as always crafty with their excuses to murder innocent civilians, stated that they don't know whether if this was the air force or the navy.
As if this really matters?
Perhaps the Israelis have run out of their creative excuses and it appears they are slanting to even completly deny the incident.

As a result of the massacare the Palestinians ended their truce and the UN has called for a full investigation. Our response? Israel has a right to defend itself, said Scott McCormack.

Children can't picnic in the beach.
