Israel’s military said it launched a ground operation along the coastal route in Beit Lahia in northern Gaza, while local health authorities reported 85 killed.

Israel said Wednesday its troops retook part of a corridor that bisects Gaza, and its defense minister warned that attacks would intensify until Hamas frees dozens of hostages and gives up control of the territory.

At least 91 Palestinians were killed and dozens wounded in airstrikes across Gaza on Thursday after Israel resumed bombing and ground operations, the enclave's health ministry said, effectively ditching a two-month-old ceasefire.

Israeli strikes killed at least 85 Palestinians across the Gaza Strip overnight and into Thursday, according to local health officials. Hours later, Hamas fired three rockets at Israel without causing casualties,

The Israeli military ordered people to evacuate an area in central Gaza near Khan Yunis, saying it would operate there in response to rocket fire from Hamas.
