Extreme speech has surged under Israeli Prime Minister Benjamin Netanyahu 's far-right government and can be heard at the highest levels ahead of Israel's Oct. 27 elections.

With just days before the vote, Israeli think tank OFEK shared a spreadsheet with The Associated Press listing 227 extreme comments made this year by officials, as part of an ongoing project tracking incitement. While Netanyahu has not used the rhetoric of his far-right allies, he campaigns with the slogan "right or Palestine," which some critics have called incitement.

Iranian-backed Houthi rebels struck a military camp for government forces in southern Yemen on Monday, killing at least 20 soldiers, Yemeni military officials said, in one of the deadliest attacks in the recent surge in fighting.

French President Emmanuel Macron on Monday began a Gulf tour aimed at securing oil and diesel supplies in an effort to bring down prices, after a weekend of violent protests sparked by soaring living costs.

Israeli Prime Minister Benjamin Netanyahu vowed Monday that Israel will not hesitate to strike its enemies at a moment's notice, eight days before a tight election and following his warnings to Iran.

Israeli police said they arrested 10 people on Monday in connection with a wave of settler violence that included attacks on a foreign journalist and European diplomats in the occupied West Bank over the weekend.

Israel had come under heavy international criticism for the attacks. Israeli police did not identify the suspects or specify their roles in the attacks, which came during a spike in settler violence during the annual Palestinian olive harvest season.

President Donald Trump on Sunday endorsed embattled Israeli Prime Minister Benjamin Netanyahu late in his reelection campaign, a coveted boost because of Trump's popularity but one that the American had withheld for months as the vote neared and the leaders' strategies in the Middle East diverged.

Trump said in a post on social media that Netanyahu "has been a Great Warrior Prime Minister, and an even greater Partner for Peace in combatting the Islamic Republic of Iran."

U.S. Vice President JD Vance — who participated in negotiations with Iran over the summer — has defended President Donald Trump's Iran strategy, and said the Trump administration is looking for a "final firm commitment from the Iranians that they're not going to rebuild their nuclear program."
