Zvi Sukkot, a member of Israel’s Knesset representing the far-right Religious Zionism Party, says it may be impossible to free all Israeli captives in Gaza and that “national security” concerns should take precedent, Al Jazeera reports.

“I wish it were possible to return all the hostages. I’m not sure that’s possible,” Sukkot told Israel’s Radio 103FM. “We need to do everything to return them but not anything that will critically harm national security.

“We think the way to return [the captives] is when Hamas understands it doesn’t have a choice but to return them,” Sukkot added, saying that he believes Israel should intensify its Rafah operation to put more pressure on the group.
