Here's a video taken by a child at the Gaza border on Monday. He screams "Allah hu Akbar" as people approach the fence (and he follows), and then he cries with joy as (according to the articles) he witnesses Gazans cutting the barbed wire.
Remember, Gaza schools - including UNRWA schools - were closed on Monday to allow as many children as possible to go to the riots.
And, as Hamas intensively hoped, for some of these children to be shot.
