The air strikes and rocket attacks between Israel and Hamas resumed Wednesday as efforts to come up with an extended ceasefire broke down.
The Israeli military said it carried out 92 air strikes in response to 1-hundred-37 rockets shot into its air space, since the truce talks broke down, which both sides blame on each other.
Hamas says an Israeli air strike on a house in Gaza killed three of its leaders, including the wife and infant son of Hamas miltary commander Mohammed Deif, who survived the attack.
In a televised statement, Hamas' military wing warned of further rocket attacks on Israel, including its main international airport.
Israeli Prime Minister Benjamin Netanyahu has promised to continue his campaign against Gaza militants "with all means and as is needed."
"Only a guarantee of the calm and safety of Israeli citizens will bring an end to this operation, and therefore I will continue to operate with firmness and insistence. Operation Protective Edge is not finished, not for a minute. We are talking about a lengthy campaign."
Egypt expressed regret over the end of the truce, adding that it will continue to try to secure a long lasting one.
The UN Security Council also voiced concerns over the resumption of fighting, calling on the parties to return to the negotiating table.
The conflict, which broke out in early July, has left at least 21-hundred people dead.
