DUBAI, United Arab Emirates >> U.S. Secretary of State Antony Blinken returned to the Mideast this week pressing for agreements to extend the Gaza cease-fire, step up the release of hostages held by Hamas and limit Palestinian civilian casualties if fighting with Israel resumed. He left Friday with his goals largely unfulfilled.

Blinken wrapped up his third Middle East tour since the Israel-Hamas war started in October with decidedly mixed results. He watched as the seven-day cease-fire agreement collapsed under new Hamas attacks and Israeli airstrikes.

And, it remained uncertain if Israel would follow through on commitments to protect Palestinian civilians from military operations in the southern Gaza Strip, as he warned they should, or whether Hamas would engage in future hostage negotiations.

Blinken arrived in Israel on Thursday with hopes to see a further extension of the cease-fire agreement under which Israel had halted most military operations in exchange for the release of hostages held by Hamas.

Blinken said Friday that Hamas bore the blame for the failure while the U.S. would continue to push for extensions to release hostages and boost the flow of humanitarian aid to Gaza. Yet, he also warned Israel that it must adhere to international laws of war as it prosecutes its campaign to eradicate Hamas.

“It came to an end because of Hamas,” Blinken said of the cease-fire. “Hamas reneged on commitments it made. In fact, even before the pause came to an end, it committed an atrocious terrorist attack in Jerusalem, killing three people, wounding others, including Americans.”

“It began firing rockets before the pause had ended and, as I said, it reneged on commitments it made in terms of releasing certain hostages. We remain intensely focused on getting everyone home, getting hostages back,” Blinken told reporters in the United Arab Emirates. “We’re still at this.”

His comments came after he met with Arab foreign ministers in Dubai on Friday to discuss the Gaza situation on the sidelines of the COP28 climate change conference. Blinken saw his counterparts from Bahrain, Egypt, Jordan, Qatar, the United Arab Emirates and the Palestinian Authority, according to the State Department.
