“They have also indicated that there are areas where there will be ‘no-strike’ zones. And in those zones, we do expect Israel to follow through on not striking,” Sullivan told reporters at the White House.
The comment came as Israel expanded its offensive in the Gaza Strip on Monday, as international concern deepened over the mounting civilian death toll of Palestinians in the overcrowded besieged territory.
The return to open warfare after a truce between Israel and Hamas expired has had ripple effects around a region on the cusp of a wider conflagration.
Israel has vowed to crush Hamas in retaliation for the militant group’s October 7 attacks, in which Israeli officials say 1,200 were killed and about 240 were taken hostage.
More than 15,500 people have been killed by Israel in Gaza since October 7, more than half of them women and children.
