Tens of thousands of displaced Palestinians began returning home to northern Gaza on Monday, bracing for what awaits them in a region that has been reduced to rubble by months of brutal bombardment and fighting.

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.

NBC News' Raf Sanchez reports on the fragile ceasefire deal between Israel and Hamas after a crisis over the weekend threatened to unravel the peace deal with a delay from Israel in allowing displaced Palestinians to return to their homes in the north of Gaza.

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.
