Relief spread across the region as Israel and Hamas moved closer to formalizing a cease-fire agreement that would lead to the release of all of the remaining hostages and potentially pave the way for an end to two years of devastating war. Songs and dances broke out on the streets of Tel Aviv. Palestinians marched through Khan Younis with glee.

President Trump, who brokered the deal, said today that he expected the remaining Israeli hostages to be released from Gaza on Monday or Tuesday in exchange for Palestinians imprisoned in Israel. He also said he was planning to travel to Egypt for a ceremonial signing of the agreement, which he described as a “momentous breakthrough” that “ended the war in Gaza.”

Many details of the agreement remained unclear. Here’s what we know: Both sides have agreed on a cease-fire, a hostage-prisoner exchange, the partial withdrawal of Israeli troops and the reopening of the Rafah crossing from Egypt to allow more aid into Gaza. But other thorny issues, like the governance of Gaza, appear to have been left for later negotiations.

Prime Minister Benjamin Netanyahu of Israel met this afternoon with his security cabinet to seek approval of the agreement. A hard-right minister said his party would not support it, but the cabinet could approve the deal without that support.

A top Hamas official echoed Trump’s confidence that the deal was “an agreement to end the war.” But that much is not yet clear. Israel’s foreign minister described it as “the implementation of the first phase.” Though more conditions must still be met, he added, “We don’t have any intention to renew the war.”
