RAFAH, Gaza Strip (AP) — Israel has ordered new evacuations in Gaza’s southern city of Rafah, forcing tens of thousands more people to move as it prepares to expand its operation. It has now evacuated the eastern third of Rafah, pushing the operation to the edges of the heavily populated central area, although the move into the city has so far been short of the full-scale invasion that Israel planned. The United Nations and other agencies have warned for weeks that an Israeli assault on Rafah would cripple humanitarian operations and cause a disastrous surge in civilian casualties. Israel also said Saturday that it is moving into an area in northern Gaza where Hamas has regrouped.
