Defense Secretary Lloyd Austin said he has ordered the Ford carrier strike group to sail to the Eastern Mediterranean to be ready to assist Israel after the attack by Hamas that has left more than 1,000 dead on both sides. Americans were reported to be among those killed and missing.

The USS Gerald R. Ford, the Navy's newest and most advanced aircraft carrier, and its approximately 5,000 sailors and deck of warplanes will be accompanied by cruisers and destroyers in a show of force that is meant to be ready to respond to anything, from possibly interdicting additional weapons from reaching Hamas and conducting surveillance.

The U.N. Security Council has held an emergency meeting behind closed doors, with the United States demanding all 15 members strongly condemn "these heinous terrorist attacks committed by Hamas," but they took no immediate action.

U.S. deputy ambassador Robert Wood said afterward that "a good number of countries" did condemn the Hamas attack but not all council members. He told reporters they could probably figure out one of them.

Israel's military scoured the country's south for Hamas fighters and guarded breaches in its border fence with tanks on Monday, as it pounded the Gaza Strip from the air and mustered for a campaign its prime minister said would destroy "the military and governing capabilities" of the militant group.

More than two days after Hamas launched its unprecedented incursion from Gaza, the military said the fighting had largely died down for now. The attack caught Israel's vaunted military and intelligence apparatus completely off guard, bringing heavy battles to its streets for the first time in decades.

The conflict between Israel and Hamas militants is making a global impact with Britain, Canada, France and Germany among nations stepping up security around potential Jewish targets as pro-Palestinian protests break out in the Middle East.

Iranian President Ebrahim Raisi said on Sunday that Iran supports the Palestinians' right to self-defense and warned Israel must be held accountable for endangering the region, a day after Hamas attacked Israel.

Palestinian militants from the Iran-backed Islamist group Hamas, which controls the Gaza strip, penetrated Israel at dawn on Saturday under the cover of a massive rocket barrage.

Israel's army said Sunday it aims to evacuate all Israelis living close to the Gaza Strip within 24 hours as it deployed tens of thousands of soldiers to fight Palestinian militants who had infiltrated into Israel.

"Our mission for the upcoming 24 hours is to evacuate all residents living around Gaza," military spokesman Daniel Hagari told reporters, adding that fighting was still on to "rescue hostages" held by militants in Israel.

Two Israeli tourists and one Egyptian were killed Sunday by a policeman in Egypt, local media and Israeli authorities said, as war rages for a second day between Israel and Hamas.

An Egyptian official said Sunday that Israel has sought help from Cairo to ensure the safety of dozens of captives and hostages held by Palestinian militants amid the ongoing war between Israel and Hamas.

The official added that Egypt’s intelligence chief had contacted Hamas and the Islamic Jihad group to seek information.

Israeli soldiers battled Hamas fighters in the streets of Israel's south on Sunday as Israel's retaliation strikes leveled buildings in Gaza.

Hamas fighters, backed by a volley of thousands of rockets, broke through barricades around Gaza early Saturday to rampage through nearby communities in Israel. They took captives back into the coastal enclave, including women, children and the elderly, while Israel's retaliation strikes leveled buildings in Gaza and its prime minister said the country was at war. Israeli media, citing rescue service officials, said at least 300 people were killed, including 26 soldiers. The health ministry in Gaza meanwhile said that at least 313 Palestinians have been killed and 1,990 wounded since the start of fighting.

U.S. President Joe Biden on Saturday decried what he called the "appalling assault" by Hamas militants and his administration pledged to ensure Israel has "what it needs to defend itself" after the surprise attack that drew worldwide condemnation and anger from Israel's allies.

Biden made clear in a call with Israeli Prime Minister Benjamin Netanyahu that "we stand ready to offer all appropriate means of support," according to the White House. He also called Jordan's King Abdullah II. Secretary of State Antony Blinken rushed to the White House for meetings and was phoning foreign counterparts, while Defense Secretary Lloyd Austin spoke with Israel's defense minister.
