Hamas says three top commanders killed by Israeli airstrike in Gaza

Hamas said that an Israel airstrike in Gaza killed three of its senior military leaders early Thursday. 
The Palestinian militant group claimed that the men -- identified as Mohammed Abu Shamaleh, Mohammed Barhoum and Raed al-Attar -- were killed along with three other people in a strike on a four-story building near Rafah, a town in the southern part of the coastal territory. 
The Israeli security agency Shin Bet confirmed the deaths of Shamaleh and al-Attar in an email, but did not mention Barhoum. The three Hamas leaders are considered to be at the senior levels of its military leadership and were involved in a number of high profile attacks on Israeli targets.
"The strike was the result of intelligence and operational activities, which led to the detection and attack on two central operatives from the heart of Hamas’s military leadership," Shin Bet said in a statement. 
The strike, one of 20 the Israeli military said it carried out early Thursday, came one day after another strike in Gaza City aimed at Hamas' senior military leader, Mohammad Dief. Israeli intelligence sources have told Fox News that they believe that Dief was killed in that operation, but Hamas has claimed that he survived. 
Israel says the airstrikes are in response to a resumption of Hamas rocket fire that on Tuesday scuttled a six-day cease-fire. The military says that only one rocket launch was registered since midnight, compared to more than 210 over the previous 30 hours.
In a nationally televised address Wednesday, Israeli Prime Minister Benjamin Netanyahu showed little willingness to return to the negotiating table after six weeks of war with Hamas.
"We are determined to continue the campaign with all means and as is needed," he said, his defense minister by his side. "We will not stop until we guarantee full security and quiet for the residents of the south and all citizens of Israel."
The Egyptian Foreign Ministry expressed "deep regret" over the breaking of the cease-fire. It said in a statement Wednesday that it "continues bilateral contacts" with both sides aimed at restoring calm and securing a lasting truce that "serves the interest of the Palestinian people, especially in relation to the opening of the crossings and reconstruction."
An Egyptian compromise proposal calls for easing the Gaza blockade but not lifting it altogether or opening the territory's air and seaports, as Hamas has demanded.
While the plan does not require Hamas to give up its weapons, it would give Western-backed Palestinian President Mahmoud Abbas, whose forces were ousted by Hamas, a foothold back in Gaza running border crossings and overseeing internationally backed reconstruction.
The Gaza blockade has greatly limited the movement of Palestinians in and out of the territory of 1.8 million people, restricted the flow of goods into Gaza and blocked virtually all exports.
Israel says the blockade is needed to prevent Hamas and other militant groups from getting weapons. Critics say the measures amount to collective punishment.
