Israeli Prime Minister Benjamin Netanyahu has vowed the Israeli military will enter Rafah, the southernmost city in Gaza where more than a million civilians are sheltering, despite continued protests from the Biden administration.

President Joe Biden spoke with Netanyahu on Monday and stressed his opposition to large-scale Israeli operations in Rafah, even as he backed Israel’s desire to go after Hamas, the terrorist group that carried out the Oct. 7 attack that left roughly 1,200 people dead, a majority of whom were civilians.
