GAZA - Dozens of Palestinian protesters in Gaza on Saturday stormed the iron gate of a border crossing with Egypt shut for the first time since it reopened late last month, Hamas border officials and witnesses said.Palestinian border officials said three buses filled with 180 passengers had waited several hours to cross the border at Rafah, the Hamas Islamist-ruled territory's gateway to Egypt, and some of those waiting responded by forcing the gate open."We have not been notified of any reason for the closure, passengers are angry," one of the officials told Reuters.
