JERUSALEM — Israel and Hamas pledged to start a cease-fire Thursday in a bid to end a year of fighting that has killed more than 400 Palestinians and seven Israelis. The deal comes as Israel also urged Lebanon to open peace talks.

The cease-fire is expected to be followed next week by an Israeli easing of its blockade of Gaza, Israeli government spokesman Mark Regev said. Talks to release an Israeli soldier held by Hamas will then intensify, Regev said.

Egypt, which brokered the talks, announced a six-month agreement on Tuesday, saying it would begin Thursday at 6 a.m.

“Thursday will be the beginning we hope of a new reality where Israeli citizens in the south will no longer be on the receiving end of continuous rocket attacks,” Regev said.

Egypt has committed as part of the deal to stop the smuggling of arms and weapons from its territory into Gaza, Israeli defense officials said. A U.S. military engineering corps is to aid the Egyptian efforts, the officials said.

If Israel determines that Egyptian anti-smuggling efforts are serious, Hamas, Egypt and European officials will begin talks on opening Gaza’s main gateway, the Rafah crossing into Egypt, Israeli defense officials said. They spoke on condition of anonymity because the sensitive talks were still in progress.
