To get the latest, follow Axios' coverage of the fighting in Israel and Gaza here.
Israeli Prime Minister Benjamin Netanyahu declared on Saturday that his country is "at war" after Hamas launched a surprise morning invasion from Gaza in the most serious incursion against Israel in decades.
The big picture: Israel is retaliating with airstrikes against Gaza. Hundreds of Israelis and Palestinians have been killed since the attack began.
President Biden in a statement on Saturday warned "against any other party hostile to Israel seeking advantage" of the situation in Israel and Gaza after Hamas launched a surprise invasion of Israeli territory.
Why it matters: Biden's statement after his call with Israeli Prime Minister Benjamin Netanyahu underscores the concern in the White House and in Israel about the possibility of the war broadening to other fronts.
Why it matters: Religion has long been a powerful force in society, touching politics, art and daily life. The rise of nonbelievers and people with no religious affiliation is diminishing its influence.
Jailed Iranian human rights activist Narges Mohammadi was awarded the Nobel Peace Prize on Friday for her fight against women's oppression and her championing of human rights.
The big picture: The prize also "recognizes the hundreds of thousands of people who... have demonstrated against the theocratic regime's policies of discrimination and oppression targeting women," including those who participated in massive protests against the death of Mahsa Amini in Iranian police custody last year, the committee said.
The warning from Sudan is dire: Nearly six months of war have created a deepening health crisis that could lead to hundreds — if not thousands — of more deaths if the fighting does not end.
The big picture: The near-total collapse of Sudan's health system underscores how the consequences of war extend far beyond the fighting — often leading to more suffering and devastation that will likely continue long after a conflict ends. That's especially true in vulnerable countries, where already strained health systems quickly buckle when fighting breaks out.
Prosecutors in Venezuela issued an arrest warrant Thursday for Juan Guaidó, the former opposition leader who's exiled in the U.S., and asked Interpol to issue a red notice.
State of play: Guaidó, who was once recognized by the U.S. and dozens of other countries as Venezuela's legitimate president, said the "accusations of the Maduro Dictatorship" of treason, usurpation of functions, money laundering and association with a view to committing a crime were "false."
