Fighting claimed lives until the final moments before the truce between Israel and Hamas took effect. For some, an unexpected delay of a few hours proved deadly.

Hundreds of thousands of Palestinians streamed into Gaza’s most heavily destroyed area on Monday after Israel opened the north for the first time since the early weeks of the war with Hamas, a dramatic reversal of their exodus 15 months ago.

More than 300,000 displaced Palestinians have now returned to the ruins of their homes in Gaza City. Mediators have begun negotiations over the second stage of the ceasefire between Israel and Hamas.
