Joy Reid leads this episode of The ReidOut with breaking coverage of the war in Israel, and the fighting that has gripped the world for the past 72 hours. Israel has declared all-out war on Hamas after the group launched a devastating surprise attack from Gaza killing 700 Israelis, many of whom were attending an outdoor concert, and abducting dozens of people, including children. Israeli Prime Minister Benjamin Netanyahu addressed his country today, saying his military would intensify its operations against Hamas and that its attacks on Gaza are "just the beginning." More than 680 people have died in Gaza, according to the Palestinian Health Ministry. Eleven Americans have been killed in the conflict and more may be missing. More than 100 people have been kidnapped. Hamas has threatened to start executing hostages if Israel bombs civilian houses in Gaza without warning.
