From news article:
The flareup occurred a day after Israeli troops shot dead three Palestinian youths in the southern Gaza town of Rafah and ignited tensions on the eve of the Bush-Sharon meeting here.
Israeli sources said the trio were involved in smuggling weapons under the border with Egypt although Palestinian sources say that they were only trying to steal a security camera.
Ok so stealing a security camera is not firing off a rocket but it's not playing soccer either, is it? No-Go zone, across razor wire, to steal a camera, warning shots fired.....
Gee what thought process do you think was winding its way around their heads while they were doing this???
