TEL AVIV — On the morning of Oct. 7, hundreds of Hamas militants switched on their GoPros and cellphones and began live-streaming the deadliest attack in Israel’s history, massacring at least 1,400 people and abducting nearly 200, according to Israeli authorities.
What began as a highly organized stealth attack, using drone technology to overtake Israeli military observation points, soon devolved into a bloody and chaotic rampage. It underscored Hamas’s capacity for sophisticated planning and indiscriminate killing; the ability of the group to conceal details of a massive offensive operation; and its struggle to manage fighters once they had bulldozed their way through Israel’s border fence.
