Yes, only Palestinians are supposed to be shown in captivity

"Israelis got a jolt last week as footage of Israeli POWs held by the Popular Front for the Liberation of Palestine in Lebanon during the 1980s aired on Al Jazeera and quickly made it to Israeli media. The footage hasn't been seen before in Israel, at least not by civilians. The video was shown as part of a three-part series on Al Jazeera about the different deals made to return Israeli soldiers, the Israeli press reports." (thanks Laleh)
