Israeli Prime Minister Benjamin Netanyahu, in a strongly worded statement, affirmed that the Israeli retaliation has just begun, and Hamas will go through much "tough and terrible" things, Times of Israel reported.
According to the Israel Air Force, the air force also attacked a headquarters spread over an area of three floors and a headquarters associated with the senior Hamas naval force, Muhammad Kashta.
According to Israel PM's Office, the war was forced on Israel in a "terrorist assault from the Gaza strip" which started at 6 am (local time) on Saturday.
In a major escalation on Saturday, Hamas launched a "surprise attack" on Israel, firing a barrage of rockets into the southern and central parts of the country.
More than 24 hours after Hamas launched rocket attacks followed by an unprecedented ground assault, firefights between forces and terrorists were ongoing in Kfar Aza, close to the Gaza border. The IDF was attempting to neutralise all terrorists still present.
While addressing a briefing on Sunday, IDF spokesman Rear Adm. Daniel Hagari said the priorities were to end the fighting in Israeli communities and control breaches in the fence dividing Gaza and Israel, CNN reported.
Following the deadly attack by Hamas that killed at least 350 people in Israel, and injured over 1500, the former Ambassador of Israel to India, Daniel Carmon has said that the country's response will not be very gentle but very forceful.
The death toll has been confirmed by the Hamas-run health ministry in the Gaza Strip that said 313 Palestinians have been killed and another 1,990 have been wounded in the Gaza Strip.
Condemning the terrorist attack in Israel by Hamas, the United Kingdom Prime Minister Rishi Sunak and Japan Prime Minister Fumio Kishida extended condolences to bereaved families.
Notably, Palestinian terrorists who entered Israel from Gaza early on Saturday morning during an 'unprecedented' incident are still being sought by Israeli security authorities in southern Israel villages.
As Israel's political-security cabinet convened late on Saturday to decide how to respond to Hamas' terror attack, Prime Minister Benjamin Netanyahu said the security to the citizens of Israel will be "restored" and the nation will win.
