Three Israeli hostages who were mistakenly shot by Israeli troops in the Gaza Strip had been waving a white flag and were shirtless when they were killed, a military official said Saturday, in Israel's first such acknowledgement of harming any hostages in its war against Hamas. Anger over the mistaken killings is likely to increase pressure on the Israeli government to renew Qatar-mediated negotiations with Hamas over swapping more of the remaining captives, believed to number more than 130, for Palestinians imprisoned in Israel. Hamas has conditioned further releases on Israel halting its punishing air and ground campaign in Gaza, while Israeli leaders have said the hostages' release can only be achieved through military pressure. The account of how the hostages died raised questions about the conduct of Israeli ground troops. Palestinians on several occasions have reported that Israeli soldiers opened fire as civilians tried to flee to safety. Hamas has claimed other hostages were previously killed by Israeli fire or airstrikes, without presenting evidence.
