Ukrainian President Volodymyr Zelensky said on Tuesday he had arrived in Saudi Arabia for talks, including about prisoners of war, following previous Saudi mediation in POW swaps with Russia.

"The kingdom's leadership has already contributed to the release of our people. I am confident this meeting will also yield results," Zelensky said on X, formerly Twitter.

U.S. President Joe Biden signaled that a cease-fire in Gaza could be at hand, saying that Israel has agreed to pause its offensive during the upcoming Muslim holy month of Ramadan if a deal is reached to release some hostages held by Hamas.

But both Israel and Hamas downplayed on Tuesday the idea that a breakthrough was imminent.

Israeli troops killed three Palestinians in an overnight raid in a refugee camp in the occupied West Bank, the Palestinian health ministry said Tuesday.

It was the latest in a surge of violence in the restive Palestinian territory since the outbreak of the Israel-Hamas war in the Gaza Strip on October 7.

The Palestinian Authority's prime minister announced his government's resignation on Monday, seen as the first step in a reform process urged by the United States as part of its latest ambitious plans to resolve the Israeli-Palestinian conflict.

But it will do little to address the authority's longstanding lack of legitimacy among its own people or its strained relations with Israel. Both pose major obstacles to U.S. plans calling for the PA, which administers parts of the Israeli-occupied West Bank, to govern postwar Gaza ahead of eventual statehood.

Israel would be willing to pause its war on Hamas in Gaza during the upcoming Muslim fasting month of Ramadan if a deal is reached to release some of the hostages held by the militants, President Joe Biden said in comments released on Tuesday.

There was no immediate Israeli reaction to Biden's comments on an emerging framework deal, brokered by the United States, Egypt and Qatar, under which Hamas would free some of the dozens of hostages it holds, in exchange for the release of Palestinian prisoners and a six-week halt in fighting. During the temporary pause, negotiations would continue over the release of the remaining hostages and additional Palestinian prisoners held by Israel.

So many sanctions. Once again, the United States, United Kingdom and European Union are hitting Russia with a new wave of sanctions over Moscow's invasion of Ukraine. This time, they come in response to the death of noted Kremlin critic Alexei Navalny, who died in an Arctic penal colony last week.

With Friday's latest round of sanctions — landing one day before the second anniversary of the war — the U.S. has targeted more than 4,000 officials, oligarchs, firms, banks and others. The EU has targeted more than 2,000 people and entities, including Russian President Vladimir Putin and his associates.

The League of Arab States on Monday called Israel's occupation of Palestinian territories an "affront to international justice", saying failure to end it amounted to "genocide".

The International Court of Justice entered its last day of week-long hearings after a request from the United Nations, with an unprecedented 52 countries giving their views on Israel's occupation.

Palestinian prime minister Mohammad Shtayyeh on Monday announced the resignation of his government which rules parts of the occupied West Bank.

"I submit the government's resignation to Mr President (Mahmoud Abbas)," Shtayyeh said, adding it comes in the wake of the "developments related to the aggression against the Gaza Strip and the escalation in the West Bank and Jerusalem".

Israel's military proposed a plan for evacuating civilians from "areas of fighting" in Gaza, Prime Minister Benjamin Netanyahu's office announced Monday, after he said a ground invasion of the Palestinian territory's southern city Rafah was necessary.

Foreign governments and aid organizations have repeatedly expressed fears that an invasion of Rafah would inflict mass civilian casualties.

An Israeli military offensive in Gaza's southernmost city of Rafah could be "delayed somewhat" if a deal is reached for a weekslong cease-fire between Israel and Hamas, Prime Minister Benjamin Netanyahu said Sunday, and claimed that total victory in the territory would come within weeks once the offensive begins.

Netanyahu confirmed to CBS that a deal is in the works, with no details. Talks resumed Sunday in Qatar at the specialist level, Egypt's state-run Al Qahera TV reported, citing an Egyptian official as saying discussions would follow in Cairo with the aim of achieving the cease-fire and release of dozens of hostages held in Gaza as well as Palestinians imprisoned by Israel.
