Delayed by a dispute over the release of a specific hostage, an agreement has been reached to allow Palestinians to return to northern Gaza.

Israel and the Palestinian Islamist group Hamas have agreed to a ceasefire in the Gaza Strip and the release of more hostages in exchange for Palestinian prisoners, mediator Qatar announced on Wednesday evening.

The truce will begin at 8:30 a.m., according to the Foreign Ministry of Qatar, a mediator in the talks. U.S. and other diplomats see the deal as the best chance to end the 15-month war that has devastated Gaza.
