“The Israeli military said on Thursday that it had apprehended hundreds of people suspected of terrorism, including wanted Hamas operatives, across the Gaza Strip in a single day, and that many had surrendered and been transferred to Israel for further questioning. Rear Adm. Daniel Hagari, the chief military spokesman, said in a televised briefing that many of the suspects under interrogation by the military and the Shin Bet domestic security agency had turned themselves over to the Israeli forces. “The intelligence we gather from the questioning aids us in the continued fight,” he said. The announcements of the surrenders and arrests came soon after photographs and videos surfaced on social media appearing to show rows of men stripped to their underwear, sitting or kneeling on the ground, with some bound and blindfolded. The New York Times has not verified the images or the video. Admiral Hagari did not answer directly when asked about the images, but reiterated the Israeli military’s goal of finding and capturing Hamas operatives. “They hide under the ground and come out and we battle them,” Admiral Hagari said. Some, he added, “come out of tunnel shafts and others out of houses. We question and investigate who among them is connected to Hamas and who is not. We detain all of them and interrogate them.””
