The Palestinians are calling it the “Great Return March”, a salute to the homes their grandparents lived in, across the border, before they fled or were pushed out by the newborn Israel. They promise to keep marching for another six weeks, at least. From Israel’s perspective, these are “acts of terror”, aimed at sabotaging the border fence and orchestrated by Hamas, the militant Islamist group that wrested control of Gaza from the Palestinian Authority (PA) in 2007 after winning an election the year before. Since then Gaza’s neighbours, Israel and Egypt, have imposed a near-total blockade on the cramped strip’s 1.8m people. But the march’s organisers insist that they do not represent any one movement, and are simply protesting against their perpetual refugee status and the siege.
