WASHINGTON -- President Donald Trump said Thursday that a deal has been reached for Hamas to disarm and Israel to withdraw its forces from Gaza, but many hurdles, conditions and long timelines remained to wind down the war in the Palestinian territory. Negotiations between Israel and Hamas had largely deadlocked over the implementation of its second phase, including the disarmament of Hamas and the reconstruction of Gaza. The official said Trump would be "very, very disappointed" if Israel didn't adhere to the agreement. Israel's retaliatory offensive in Gaza has killed more than 73,000 Palestinians, including those killed since the ceasefire, Gaza's Health Ministry said. Israel's military now controls more than half of Gaza, leaving Palestinians confined to squalid tent camps and heavily damaged urban neighborhoods.
