The war, which has already claimed at least 1,800 lives on both sides, is only expected to escalate. The weekend attack that Hamas said was retribution for worsening Palestinian suffering under Israeli occupation has fired Israel’s determination to crush the group’s hold in Gaza — hiking risks of an expanded regional conflict.

Israel on Sunday formally declared war on Hamas in response to the unprecedented attack, which has killed at least 900 people in Israel, Israel’s Army Radio reported Monday. At least 2,506 people have been injured, the Israeli Health Ministry said earlier. The Israeli strikes have killed at least 560 people, including dozens of children, and left 2,900 injured, according to the Palestinian Ministry of Health.

The divide was reflected in his audience. While lawmakers repeatedly rose to their feet in thundering applause of President Isaac Herzog’s recounting of Israel’s founding, a handful of leading young progressive Democrats boycotted his speech.

Israeli police on Sunday entered the Al-Aqsa Mosque compound in Jerusalem's Old City to secure the way for Jewish visitors to the flashpoint holy site, fueling clashes that left 17 Palestinians wounded, according to Palestinian medical workers.

The Holocaust, World War II and Nazism have been important tools for Putin in his bid to legitimize Russia’s moves in Ukraine, but historians see their use as disinformation and a cynical ploy to further the Russian leader’s aims.

Secretary of State Antony Blinken announced Tuesday that the U.S. would reopen its consulate in Jerusalem — a move that restores ties with Palestinians that had been downgraded by the Trump administration.

The cease-fire that took effect Friday appears to have halted 11 days of fighting between Israel and Gaza’s militant Hamas rulers, without resolving any of the underlying issues in the decades-old Middle East conflict.

 Palestinians rallied by the thousands Friday after a cease-fire took effect in the latest Gaza war, with many viewing it as a costly but clear victory for the Islamic militant group Hamas. Israel vowed to respond with a “new level of force” to further hostilities.

President Joe Biden expressed support for a cease-fire between Israel and Gaza’s militant Hamas rulers in a call to Israeli Prime Minister Benjamin Netanyahu on Monday, the eighth day of air strikes and rocket barrages that have killed at least 200 people, most of them Palestinians in Gaza.
