An agreement has been reached between Israel and Hamas that involves the release of additional hostages and the return of Palestinians to the northern part of the Gaza Strip.

Israel has prevented thousands of Palestinians from returning to northern Gaza, accusing Hamas of violating the terms of a fragile ceasefire by changing the order of hostages it has released.

Palestinian officials say more than 650,000 displaced people were blocked from entering the northern Gaza Strip, according to Reuters. Israel blocked access to the region after it accused Hamas of failing to release 29-year-old Arbel Yehud during an agreed upon hostage-prisoner exchange.
