Polling centers in Egypt opened Monday, the second voting day in a presidential election that is certain to see President Abdel Fattah el-Sissi secure another term.

The vote, which began across the Middle Eastern nation on Sunday, has been overshadowed by the Israel-Hamas war in Gaza, on Egypt's eastern borders.

Russia fired eight ballistic missiles at Kyiv early Monday, all of which were shot down, Ukraine's Air Force said. The thwarted attack still left one person injured by shrapnel and three more suffered severe stress reactions, officials said.

A series of loud explosions rang out in Ukraine's capital just after 4 a.m., as the city was under its nightly curfew, followed by air raid sirens.

Israel said it is prepared to fight for months or longer to defeat Gaza's Hamas rulers, as its ground offense intensifies with more airstrikes and artillery fire.

Qatar, which has played a key mediating role, says efforts to stop the war and have all hostages released will continue, but a willingness to discuss a cease-fire is fading.

A British Palestinian surgeon who spent weeks in the Gaza Strip during the current Israel-Hamas war as part of a Doctors Without Borders medical team said he has given testimony to a British war crimes investigation unit.

Ghassan Abu Sitta, a plastic surgeon specializing in conflict medicine, has volunteered with medical teams in multiple conflicts in Gaza, beginning as a medical student in the late 1980s during the the first Palestinian uprising. He has also worked in other conflict zones, including in Iraq, Syria and Yemen.

Heavy fighting raged overnight and into Sunday in the southern Gaza town of Khan Younis, as Israel pressed ahead with its offensive after the U.S. blocked the latest international efforts to halt the fighting and rushed more munitions to its close ally.

Israel has faced rising international outrage and calls for a cease-fire after the killing of thousands of Palestinian civilians and the displacement of nearly 85% of Gaza's 2.3 million people within the besieged territory, where U.N. agencies say there is no safe place to flee.

Egyptians began voting Sunday in a presidential election in which President Abdel Fattah al-Sisi faces no serious challenger and is certain to win another term, keeping him in power until 2030.

The election has been overshadowed by the Israel-Hamas war in Gaza. Almost all Egyptians' attention has been on the war on their country's eastern borders and the suffering of Palestinian civilians in the coastal enclave.

Israeli warplanes struck parts of the Gaza Strip overnight into Saturday in relentless bombardments, including some of the dwindling slivers of land Palestinians had been told to evacuate to in the territory's south.

The latest strikes came a day after the United States vetoed a United Nations resolution demanding an immediate humanitarian cease-fire in Gaza, despite it being backed by the vast majority of Security Council members and many other nations. The vote in the 15-member council was 13-1, with the United Kingdom abstaining.

The United States has vetoed a United Nations resolution backed by almost all other Security Council members and dozens of other nations demanding an immediate humanitarian cease-fire in Gaza. Supporters called it a terrible day and warned of more civilian deaths and destruction as the war goes into its third month.

The vote in the 15-member council was 13-1, with the United Kingdom abstaining. The United States' isolated stand reflected a growing fracture between Washington and some of its closest allies over Israel's monthslong bombardment of Gaza. France and Japan were among those supporting the call for a cease-fire.

One of the biggest and brightest stars in the night sky will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse.

The rare and fleeting spectacle, late Monday into early Tuesday, should be visible to millions of people along a narrow path stretching from central Asia's Tajikistan and Armenia, across Turkey, Greece, Italy and Spain, to Miami and the Florida Keys and finally, to parts of Mexico.

Ongoing catastrophic rains in Eastern Africa have been worsened by human-caused climate change that made them up to two times more intense, an international team of climate scientists said Thursday.

The analysis comes from World Weather Attribution, a group of scientists who examine whether and to what extent human-induced climate change has altered the likelihood and magnitude of an extreme-weather event.
