The cease-fire goes into effect at 6 a.m. Thursday. Hamas and Israel cease all operations against each other in the Gaza Strip.
After three days of quiet, Israel will begin easing restrictions on the crossings into Gaza and will allow in 30 percent more vital supplies than the amount currently transferred into the Strip.
If the cease-fire is upheld, Israel will continue to allow in more supplies gradually.
Egypt will crack down on smuggling under the Philadelphi Corridor from Sinai. Earlier this week, American military engineers installed tunnel-detection devices there.
Egypt will renew talks with Hamas next week for the release of Gilad Schalit. Israeli negotiator Ofer Dekel will then travel to Cairo to finalize the deal.
If progress is made in the negotiations, Israel will allow the reopening of the Rafah crossing between Egypt and Gaza under EU supervision.
