Israeli military strikes killed at least 22 Palestinians across the Gaza Strip on Wednesday, as Israeli forces deepened their incursion into Beit Hanoun town in the north, forcing most remaining residents to leave.

Israeli airstrikes killed at least 46 people in the Gaza Strip in the past day, including 11 at a makeshift cafeteria in an Israeli-declared humanitarian zone, medics said. In Lebanon, warplanes struck Beirut's southern suburbs and killed 33 people elsewhere in the country on Tuesday.

Palestinian medics say an Israeli strike on a home in northern Gaza killed three siblings aged 6 and under. They were among at least six people killed in Israeli strikes on Tuesday in the war-ravaged territory,
