Israelis were left stunned and speechless when three hostages held by Hamas were killed by Israeli forces in the middle of an active war zone after they waved a white flag and screamed out in Hebrew to show they did not pose a threat.

For some, the incident was a shocking example of the ugliness of war, where a complex and dangerous battlefield is safe for no one. But for critics, the incident underscores what they say is the excessively violent conduct of Israel's security apparatus against Palestinians. Except in this case, it cut short the lives of three Israelis trying desperately to save themselves.

Nearly 70% of Iran's gas stations went out of service on Monday following possible sabotage — a reference to cyberattacks, Iranian state TV reported.

The report said a "software problem" caused the irregularity in the gas stations. It urged people not to rush to the stations that were still operational.

The Israeli military said it has discovered a large tunnel shaft in Gaza close to what was once a busy crossing into Israel, raising new questions about how Israeli surveillance missed such conspicuous preparations by Hamas for the militants' deadly Oct. 7 assault.

The entryway to the tunnel is just a few hundred meters from the heavily fortified Erez crossing and a nearby Israeli military base.

Iraqis voted Monday in the first provincial council elections in a decade, which are expected to strengthen powerful pro-Iran Shiite Muslim groups.

The vote comes at a time of widespread public disillusionment in the oil-rich and corruption-plagued country of 43 million people.

Defense Secretary Lloyd Austin was expected to press Israel to wind down major combat operations in Gaza on a visit Monday, in the latest test of whether the U.S. can leverage its unwavering support for the offensive to blunt its devastating impact on Palestinian civilians.

France, the U.K. and Germany, some of Israel's closest allies, joined global calls for a cease-fire over the weekend, and Israeli protesters have demanded the government relaunch talks with the militant group on releasing more hostages after three were mistakenly killed by Israeli troops while waving a white flag.

Israel pressed ahead with its Gaza offensive on Sunday after a series of shootings, including of three hostages who were shirtless and waving a white flag, raised questions about its conduct in a 10-week-old war that has brought unprecedented death and destruction to the coastal enclave.

Gaza remained under a communications blackout for a fourth straight day — the longest of several outages over the course of the war, which aid groups say complicate rescue efforts after bombings and make it even more difficult to monitor the war's toll on civilians.

Three Israeli hostages who were mistakenly shot by Israeli troops in the Gaza Strip had been waving a white flag and were shirtless when they were killed, military officials said Saturday, in Israel's first such acknowledgement of harming any hostages in its war against Hamas.

Prime Minister Benjamin Netanyahu said in a nationwide address that the killings "broke my heart, broke the entire nation's heart," but he indicated no change in Israel's intensive military campaign. "We are as committed as ever to continue until the end, until we dismantle Hamas, until we return all our hostages," he said.

A U.S. warship shot down 14 suspected attack drones over the Red Sea on Saturday, and a Royal Navy destroyer downed another drone that was targeting commercial ships, the British and American militaries said.

Houthi rebels in Yemen have launched a series of attacks on vessels in the Red Sea, one of the world's busiest shipping routes, and have launched drones and missiles targeting Israel, as the Israel-Hamas war threatens to spread.

The top two U.S. military leaders are traveling to Tel Aviv to advise the Israeli government on how to transition from major combat operations against Hamas in Gaza to a more limited campaign and prevent a wider regional war. Their trip comes as Iranian-backed militants on Saturday launched a wave of attack drones against ships in the Red Sea and said they would continue until Israel's "aggression" ends.

One of the American warships assigned to the Ford carrier strike group, the destroyer USS Carney, "successfully engaged" 14 one-way attack drones launched from Houthi-controlled areas of Yemen, U.S. Central Command said in a statement. Britain reported that a Royal Navy destroyer downed another drone that was targeting commercial ships.

Kuwait's ruling emir, the 86-year-old Sheikh Nawaf al-Ahmad Al-Sabah, has died, state television reported Saturday.

Kuwait TV broke into programming with Quranic verses just before making the announcement.
