Israeli strikes killed dozens of people including children on Sunday in Lebanon and isolated northern Gaza, as the world watched for signs of how the U.S. election might affect the wars between Israel and Iranian-backed militant groups Hamas and Hezbollah.

Palestinian officials say an Israeli strike hit a tent sheltering a displaced family in the central Gaza Strip, killing at least three people including the parents of twins.

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