The opening was delayed over a dispute between Hamas and Israel, which said the militant group had changed the order of the hostages it released in exchange for Palestinian prisoners.

Palestinians trying to return to northern Gaza were stranded on two highways in a standoff that threatened to undo the shaky peace between Israel and Hamas.

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.
