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

Israel's military has warned that Hamas militants from Gaza are still fighting inside Israel after they infiltrated southern communities and left a reported 300 people dead. Prime Minister Benjamin Netanyahu has told Israelis they are going into a "long and difficult war".

An Israeli airstrike killed at least 23 people in the village of Aalmat, north of Beirut and far from the areas in southern and eastern Lebanon where the militant Hezbollah group has a major presence. Lebanon's Health Ministry said a further six people were wounded. There was no immediate Israeli comment.
