Israel let tens of thousands of Palestinians go back to northern Gaza for the first time since the early weeks of the 15-month war with Hamas​, under terms of a fragile ceasefire​.

Israel on Monday began allowing Palestinians to return to the heavily destroyed north of the Gaza Strip for the first time since the early weeks of the 15-month war with Hamas, in accordance with a fragile ceasefire.

Massive crowds streamed into the most heavily destroyed part on Monday in accordance with a fragile ceasefire.

Israel on Monday began permitting thousands of Palestinians to return to the devastated northern Gaza Strip for the first time since the early weeks of the 15-month conflict between Israel and the militant group Hamas. The move comes as part of a fragile ceasefire agreement currently in place.

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.

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.

An unending stream of people marched up the coast of Gaza on Monday, carrying their belongings in plastic bags and repurposed flour sacks through the central city of Nuseirat after Israel reopened access to the territory's north.

Even before the first phase is completed, the fragile cease-fire agreement that has paused 15 months of war in Gaza between Israel and Hamas faces increasingly long odds of lasting or even reaching phase two.

Palestinians began returning to the north of the war-battered Gaza Strip on Monday after Israel and Hamas said they had reached a deal for the release of another six hostages.The breakthrough preserves a fragile ceasefire in the Israel-Hamas war,

Hamas apparently does not insist on retaining control over the Gaza Strip and would not accept any power other than its own in the coastal strip,

Long lines of Palestinians -- some kneeling to kiss the soil as they stepped into the northern part of the strip -- were making their way home on Monday.
