At 6:30 a.m. on Saturday, October 7,  Hamas, the Iran-backed terror group controlling Gaza, launched an unprovoked and vicious surprise attack on Israel. Using rockets, paragliders, boats, motorcycles and other vehicles, and whatever other means they could, terrorists infiltrated Israel with one goal—to murder and kidnap Israelis.

Over 800 Israelis have been killed and more than 2,500 are critically wounded. There are multiple reports of hostages being taken. More than 4,400 rockets have been fired at Israeli towns and cities. Israeli families are huddled in bomb shelters.
