“The fragile cease-fire between Israel and Hamas was back on track Sunday as the militants freed 17 more hostages, including 14 Israelis and the first American, in a third exchange under a four-day truce that the United States said it hoped would be extended. In turn, Israel released 39 Palestinian prisoners. Most hostages were handed over directly to Israel, waving to a cheering crowd as they arrived at an air force base. Others left through Egypt. Israel’s army said one was airlifted to a hospital, and the director of Soroka Medical Center said Elma Avraham, 84, was in life-threatening condition as “a result of an extended period of time when an elderly woman was not taken care of as needed.” The youngest hostage released was Abigail Edan, a 4-year-old girl and dual Israeli-American citizen whose parents were killed in the Hamas attack that started the war on Oct. 7. “What she endured was unthinkable,” U.S. President Joe Biden said of the first American freed under the truce. He did not know her condition and did not provide updates on other American hostages. Biden said his goal was to extend the cease-fire deal as long as possible.”
