The Biden administration has pressed Israel to delay its imminent invasion of Gaza to allow for the release of more hostages held by Hamas and for aid to reach Gaza, according to two sources briefed on the discussions.

The release of two Americans held by Hamas Friday signaled that more of roughly 200 people believed to be kidnapped by the militant group may be freed after they were taken during the group’s deadly attacks launched against Israel two week ago.

“The [administration] pressed Israeli leadership to delay because of progress on the hostage front,” and the need to get trucks of aid into Gaza, one person familiar with the discussions said.
