The October 7 massacre was a brutal series of terrorist attacks along the Gaza border, when Hamas terrorists under the cover of a barrage of rocket fire infiltrated several Israeli towns, cities, and IDF bases.
The resulting attacks stretched as far east as Ofakim in the Negev and resulted in at least 1,200 people murdered and hundreds taken hostage by Hamas back to Gaza.
Occurring on the morning of the Simchat Torah holiday, the October 7 massacre kicked off Operation Swords of Iron, the code name for Israel's war against Hamas in Gaza.
