Israel said its forces had returned to northern Gaza to fight a Hamas resurgence. That has brought a new round of suffering for residents.

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.

In anticipation of a possible Israeli strike, Iran's Islamic Revolutionary Guard Corps (IRGC) has placed all its units on high alert, preparing for countermeasures by land, sea, and air.

Israel's new defense minister, Israel Katz, has hinted that Israel has an "opportunity" to target Iran's nuclear program. He has also told military officials there will be no cease-fire with Hezbollah.
