Some troops had been expected to withdraw to allow hundreds of thousands of displaced Gazans to go home. But Israel said the hostage exchange before that step had not gone as agreed. Hamas accused Israel of stalling.

All four hostages are female Israeli soldiers. They are expected to be released Saturday in accordance with a ceasefire agreement with Israel that's halted fighting in the Gaza war since last weekend.
