As Israel’s forces push back into Gaza after a two-month ceasefire with Hamas, its political and military leaders are considering plans for a fresh ground campaign.

More than 50,000 Palestinians have been killed in Gaza since Israel’s war with Hamas began, the territory’s health ministry said Sunday, a grim milestone for a war with no end in sight as Israel resumes fighting and warns of even tougher days ahead.

Egypt has floated a new proposal aimed at restoring the Gaza ceasefire deal, security sources told Reuters on Monday, as Palestinian health authorities said Israeli strikes had killed at least 65 people in the enclave in the previous 24 hours.
