Tens of thousands of Hamas supporters massed in Gaza City on Sunday to mark the 21st anniversary of the creation of the Islamist movement which seized control of the Gaza Strip last year. In an address to the crowds, Ismail Haniya, the head of the Hamas administration in Gaza, boasted that US President George W. Bush's administration had failed to defeat his movement, which had only grown stronger. "Bush declared war on the Palestinian people... He provided money and arms to the seditionists to wage a war against legality," Haniya said, referring to the deadly streetfighting with loyalists of Western-backed president Mahmud Abbas that preceded Hamas's takeover of Gaza. "Bush failed, we have not been overthrown," he said. And despite Israel's blockade of the territory, "Hamas is stronger and will remain stronger because it draws its strength from God."
