Under the cease-fire deal, Ms. Yehud should have been among the first two groups of hostages released on Jan. 19 and Jan. 25, but she was not freed.

Hamas has set up a stage in northern Gaza’s Jabalia ahead of this morning’s planned hostage release, Palestinian media has reported. The Red Cross is preparing to receive female lookout Agam Berger, 20, female civilian Arbel Yehud, 29, Gadi Moses, 80, and five Thai nationals.
