The Israeli strike hit a mosque where displaced people were sheltering in the Gaza town of Deir al Balah. A year after Hamas' Oct. 7 attack on Israel, a new front has opened in Lebanon.

A day before it marks a year since the deadly Oct. 7 attacks by Hamas, Israel is locked into a multi-front war with no clear end, sending troops back to northern Gaza and keeping up intense aerial attacks and a limited ground maneuver in Lebanon.

Israel has been expanding its actions in Lebanon. On Saturday, it made its first strike in the northern city of Tripoli, a Lebanese security official said, and Israeli troops launched raids in the south.
