Israeli strikes killed at least 86 Palestinians across the Gaza Strip since the announcement of a ceasefire between Israel and Hamas on Wednesday, officials said.

Israel approved a cease-fire agreement with Hamas early Saturday, setting up the first reprieve in Gaza in over a year. Palestinians have celebrated the truce with the hope that it will finally end the devastating 15-month war, and Israelis are anxiously awaiting the return of scores of captives abducted by Hamas.
