Palestinian medics said Israeli airstrikes killed at least 31 people in Gaza on Sunday.
Almost half of the deaths occurred in northern areas, health officials said, where Israel Defense Forces troops are pressing an intense campaign intended to root out surviving Hamas fighters and stop its units from regrouping.
The Hamas-run Gaza Health Ministry said Monday that around 1,800 people have been killed and 4,000 injured by Israel's north Gaza campaign, with "widespread destruction of hospitals and infrastructure."
