More than 375,000 Palestinians have made their way back to homes in northern Gaza after 15 months on the run because of war.

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.

Hamas provided Israel with long-awaited information about the status of the hostages listed for release during the first phase of the ceasefire agreement in the war in the Gaza Strip. The move followed intense negotiations over the weekend to resolve a dispute that had threatened to derail the deal.

Eight of the remaining hostages set to be released by Hamas in the first phase of a ceasefire agreement with Israel are dead, according to an Israeli government spokesperson.

Israel has said the next release of hostages will take place on Thursday, followed by another on Saturday. The ceasefire is aimed at winding down the deadliest and most destructive war ever fought between Israel and Hamas and securing the release of dozens of hostages captured in the militants’ Oct.
