Before wrapping up his trip to the Middle East, Secretary of State Antony Blinken spoke to members of the media on a tarmac in Qatar, emphasizing the urgency behind the latest push for a hostage release and cease-fire agreement in Gaza.

"Our message is simple, it's clear, and it's urgent. We need to get the cease-fire and hostage agreement over the finish line, and we need to do it now," he said.

"Time is of the essence, because with every passing day, the well-being and lives of the hostages are in jeopardy. Time is of the essence, because every single day, women, children, men in Gaza are suffering," he said. "And time is of the essence because with every passing day, there's the danger of escalation in the region."

Blinken said Qatar and Egypt remain "in direct contact with Hamas working to bring it along" with the bridging proposal, but he again made clear that even if that were to happen, all sides would still need to complete "detailed implementation agreements that go along with putting the cease-fire into effect."

Israeli Prime Minister Benjamin Netanyahu told representatives of the hostage families that "Israel will not under any circumstances withdraw from the Philadelphie axis and the Netzer Corridor despite tremendous pressure to do so," according to a release from the Tikva Forum of hostage families.

"I'm not sure there will be a deal, but if there is a deal -- the deal will be one that preserves the interests that I repeat over and over again, which are the preservation of Israel's strategic assets. The demand that there be negotiations, even in the future -- a demand that is unacceptable, even if there is a deal -- after 42 days, we will return to fighting immediately, until the elimination of Hamas, even while negotiating the next steps," Netanyahu told hostage families.

"The military pressure will continue with full force, this is the only thing that makes Hamas drop its unreasonable demands," Netanyahu added.

Asked by ABC News, Netanyahu's office said they had nothing to add beyond a press release that did not include the comments.
