Israel has addressed many of President Joe Biden's concerns over its long-simmering plan to carry out a widescale military operation in the southern Gaza city of Rafah aimed at rooting out Hamas, a senior Biden administration official said Tuesday.

The official, who was not authorized to comment publicly and requested anonymity, said that in talks over the weekend with White House national security adviser Jake Sullivan, Israeli officials incorporated many changes into their planning that seem to meet concerns about deepening an operation in an area that has been flooded with Palestinian refugees during the seven-month war.
