The IDF continued Friday to block Palestinian attempts to breach the border fence from the Gaza Strip, after declaring the border region a closed military zone. After twice attempting to lob explosives and firebombs across the fence, while attempting to break through, the Palestinians claimed four dead and 350 injured by IDF fire and tear gas. The few thousand Palestinian demonstrators Friday were a fraction of last week’s turnout for Hamas’ March of Return. By late afternoon, the crowd was scattering and the change of wind blowing the black smoke emitted by thousands of flaming tires back into the Gaza Strip and away from the border. Hamas aims to make the first two weeks of disturbances the start of a drawn-out, march-on-Israel event to reach its climax on May 15. The IDF is digging in for the long haul.
