More than 600 Palestinians jailed in Israel will be freed in exchange, the Palestinian prisoners media office said Friday. They include 50 serving life sentences, 60 with long sentences, 47 who were released under a previous hostage-for-prisoner exchange and 445 Palestinians who were seized by Israeli troops in Gaza since the war began.

Hamas freed three Israelis who appeared to be in relatively good condition, and Israel released 369 Palestinian prisoners. The exchange will likely sustain a fragile cease-fire, at least for now.
