DEIR AL-BALAH, Gaza Strip — Israeli strikes killed dozens of people including children on Sunday in Lebanon and northern Gaza, where the military has waged a major offensive for more than a month that aid groups say has worsened the humanitarian crisis in the besieged enclave.

Rescue workers were still searching the rubble after the strike in the village of Almat, in the Jbeil district of Lebanon, the country’s health ministry said.
