Israel's counteroffensive into Gaza extended through the night, including airstrikes in Gaza City, home to Hamas' centers of government.
Israeli warplanes pounded downtown Gaza City with relentless bombardments into early Tuesday, after Israel’s prime minister vowed retaliation against the Islamic militant group that would "reverberate for generations."
Israeli Prime Minister Benjamin Netanyahu gave a nationally televised address, where he said: "We have only started striking Hamas."
He added: "What we will do to our enemies in the coming days will reverberate with them for generations."
