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.

Hezbollah's deputy leader Sheikh Naim Qassem has warned that the group has much more weapons to use if Israel expands the war.

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.

It was the puddles of green sludge left by the tires of massive tractors in western Belgium's industrial farmlands that drew the attention of biological engineer Ineke Maes.

Associates of Russian opposition leader Alexei Navalny said Monday that talks were underway shortly before his death to exchange him for a Russian imprisoned in Germany.

"Alexei Navalny could have been sitting here now, today. It's not a figure of speech," Maria Pevchikh, who lives outside Russia, said in a video statement. She said she received confirmation the talks were in the "final stages" on Feb. 15, the day before Navalny was reported dead.
