Officials representing Israel and Hamas said today that the two sides had agreed to a 42-day cease-fire that would coincide with the release of Israeli hostages who have been held captive in Gaza. The final details are still being worked out, but the tentative agreement raised hopes that there could soon be an end to the war.

The complex ceasefire accord between Israel and militant group Hamas, which controls Gaza, emerged on Wednesday after months of mediation by Qatar, Egypt and the U.S. and 15 months of bloodshed that devastated the coastal territory and inflamed the Middle East.
