More than 80 people have been killed in Israeli strikes in Lebanon, northern Gaza and Syria since late Saturday, according to reports.

Lebanon, Syria and the Gaza Strip have witnessed heavy airstrikes in the past days, amid renewed efforts to appease the situation in the region.

The latest bombardment came as the U.S. said it would not reduce its military support for Israel after a deadline passed for allowing more humanitarian aid into Gaza.

Israeli strikes killed dozens of people on Sunday in Lebanon and the northern Gaza Strip, where the military has been waging a major offensive for more than a month that aid groups say has further worsened the humanitarian crisis in the besieged enclave.

Israeli airstrikes killed at least 46 people in the Gaza Strip in the past 24 hours, including 11 at a makeshift cafeteria in an Israeli-declared humanitarian zone, medics said. In Lebanon, warplanes struck Beirut's southern suburbs and killed 18 people elsewhere in the country on Tuesday.

Israeli strikes have killed dozens of people including children in Lebanon and northern Gaza. Meanwhile, the world is watching for signs of how the U.S. election might affect the war.
