Israeli President Isaac Herzog and his Palestinian counterpart Mahmoud Abbas will both address the COP28 U.N. climate talks in Dubai this week, seven weeks into the Israel-Hamas war, officials said on Tuesday.

Herzog and Abbas are both scheduled to make speeches lasting three minutes maximum on Friday. Abbas is expected to be in the room when Herzog is speaking, as he is scheduled to address the room only three speakers later.

Hamas said Tuesday that it clashed with Israeli forces after they violated the truce in northern Gaza, while noting that it is still committed to the temporary ceasefire.

CIA Director William Burns arrived in Qatar on Tuesday for secret meetings with Israel’s spy chief and Qatar’s prime minister aimed at brokering an expansive deal between Israel and Hamas, three people familiar with the visit told the Washington Post.

The Biden administration has told Israel that it must work to avoid "significant further displacement" of Palestinian civilians in southern Gaza if it renews its ground campaign aimed at eradicating the Hamas militant group, senior U.S. officials said.

The administration, seeking to avoid more large-scale civilian casualties or mass displacement like that seen before the current temporary pause in the fighting, underscored to the Israelis that they must operate with far greater precision in southern Gaza than they did in the north, the officials said, briefing reporters on condition of anonymity under ground rules set by the White House.

Mediator Qatar said Tuesday it would use a two-day extension to a humanitarian pause in Gaza to work towards a "sustainable truce" between Israel and Hamas.

"Our main focus right now, and our hope, is to reach a sustainable truce that will lead to further negotiations and eventually to an end... to this war," foreign ministry spokesman Majed Al Ansari told a Doha news conference.

From Lebanon, Palestinian Fatima al-Ashwah has been praying for relatives in Gaza, but received grim news that Israeli bombing killed around 12 of them days before a temporary truce between Israel and Hamas.

"They bombed their house," leaving some of them "in pieces," said Ashwah, drained by weeks of anguish and days of grief.

U.S. Secretary of State Antony Blinken will return this week to the Middle East as the U.S. hopes to find a way to extend a cease-fire in Gaza and get more hostages released, the State Department said Monday. It will be his third trip to the region since Israel's war with Hamas began last month.

Blinken will travel to Israel and the West Bank after attending Ukraine-focused meetings on Tuesday and Wednesday in Brussels and Skopje, North Macedonia, where foreign ministers from NATO and the Organization for Peace and Security in Europe are gathering.

A truce between Israel and Hamas entered its fifth day on Tuesday, with the militant group promising to release more civilian hostages to delay the expected resumption of the war and Israel under growing pressure to spare Palestinian civilians when the fighting resumes.

The sides agreed to extend their truce through Wednesday, with another two planned exchanges of militant-held hostages for Palestinians imprisoned by Israel. But Israel has repeatedly vowed to resume the war with "full force" to destroy Hamas once it's clear that no more hostages will be freed under the current agreement's terms.

The United States welcomed an agreement Monday to extend a truce between Israel and Hamas by two days, saying it was hopeful the humanitarian pause would continue for longer still.

A truce between Israel and Hamas in the Gaza Strip will be extended by two days, the Palestinian group and mediator Qatar said Monday, opening the way for further releases of hostages and prisoners.

With just hours to go before the so-called "humanitarian pause" was to end early Tuesday, Hamas said that an agreement had been reached to prolong it by 48 hours under the existing terms.
