The death count in Israel has surged above 1,200 from the worst attack in the country's history, while Gaza officials have reported 765 people killed so far. Israel army also said it had recovered the bodies of around 1,500 Hamas militants inside Israel. Hamas has threatened to execute one hostage every time Israel drops a bomb, without warning, on a Palestinian home in the Gaza Strip. "Every targeting of our people without warning will be met with the execution of one of the civilian hostages," the armed wing of Hamas has warned Israel. The group has 150 hostages - including children.
