Hundreds of thousands of displaced Palestinians returning to their homes in northern Gaza have passed through checkpoints in a central zone of the enclave where scanners check for concealed weapons being taken in cars and vehicles.

Delayed by a dispute over the release of a specific hostage, an agreement has been reached to allow Palestinians to return to northern Gaza.

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.
