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.

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.

Israel previously threatened Gaza with "complete destruction and devastation"​ if Hamas didn't hand over the remaining hostages.
