Hamas threatens to execute a captive every time Israel bombs a Palestinian home as rocket attacks on Lebanon kill three Hezbollah militants

    Hamas tells residents of Israel's Ashkelon to leave within hours.

    Abu Ubaida, a spokesman for the terror group, has told residents of the Israeli port city of Ashkelon to leave the area by 5 p.m on Tuesday, without providing further details.

    Ashkelon has a population of over 100, 000 people and is situated just 8 miles north of the Gaza Strip.

    The Islamist militant Hamas movement threatened to execute an Israeli captive every time Israel bombs a Palestinian home without warning.

    It comes as Israel called up an unprecedented 300,000 reservists and imposed a blockade on the Gaza Strip, raising fears it planned a ground assault.

    The violence, which has claimed more than 1,500 lives, prompted international declarations of support for Israel after a devastating weekend attack by Hamas, and appeals for an end to the fighting and protection of civilians.

    Israeli TV channels said the death toll from the Hamas attack had climbed to 900 Israelis, with at least 2,600 injured, and dozens taken captive. Among the Israeli dead were 260 mostly young people gunned down at a desert music festival, where some of the hostages were abducted.

    Tobias Ellwood, Britain's former chairman of the Foreign Affairs Committee said the scale and complexity of the surprise attack suggested Iran was behind the operation.

    Speaking to TalkTV's Jeremy Kyle and Nicola Thorp, she said: "Terrorism must be defeated," he said. "Hamas and Islamic Jihad must be neutralised. But I say this with caution, we'd be wise to learn from the past.

    "We now appreciate some grave strategic areas were made, however well intentioned, under the banner of defeating terrorism back in 2001. No doubt, Iran is calling the shots here, such was the complexity of this operation.

    "Hamas could not have done this without external support. I suspect Hezbollah in Lebanon was involved as well. And we've yet to see what they intend to do next."

    Israeli Prime Minister Benjamin Netanyahu vowed revenge in a fiery speech accusing Iran-backed Hamas of executing tied-up children and other atrocities. "This vile enemy wanted war and it will get war," he said.

    Gaza's Health Ministry said at least 687 Palestinians had been killed and 3,726 wounded in Israeli air strikes on the blockaded enclave since Saturday. Apartment blocks, a mosque and hospitals were among the sites attacked, and the strikes destroyed some roads and houses, according to media reports and eyewitnesses.

    Israel also bombed the headquarters of the private Palestinian Telecommunication Co., which could affect landline telephone, internet and mobile phone services.

    The strikes continued into the night on Monday. The Israeli military said it hit targets in the Gaza Strip from the sea and air, including a weapons depot it said belonged to Islamic Jihad and Hamas targets along Gaza's coast line.

    Hamas spokesperson Abu Ubaida issued the threat on Monday to kill Israelis among the dozens held captive after the surprise attack on Saturday morning. He said Hamas would execute an Israeli captive for every Israeli bombing of a civilian house without warning, and broadcast the execution.

    There was no immediate response from the Israeli military to that threat. Israeli Foreign Minister Eli Cohen said more than 100 people had been taken captive by Hamas during the deadly cross-border incursion over the weekend.


    Palestinians reported receiving calls and mobile phone audio messages from Israeli security officers telling them to leave areas mainly in the northern and eastern territories of Gaza, and warning that the army would operate there.

    Dozens of people in Gaza City's Remal neighbourhood fled their homes.

    "We took ourselves, children and grandchildren and daughters-in-law and we ran away. I can say that we became refugees. We don't have safety or security. What's this life? This is not a life," resident Salah Hanouneh, 73, said.

    In Israel's south, scene of the Hamas attack, Israel's chief military spokesperson said troops had re-established control of communities inside Israel that had been overrun, but isolated clashes continued as some gunmen remained active.

    Sirens warning of incoming rocket fire blared in Israeli communities near the Gaza border overnight.

    The announcement that 300,000 reservists had been activated in just two days added to speculation that Israel could be contemplating a ground assault of Gaza, a territory it abandoned nearly two decades ago.

    "We have never drafted so many reservists on such a scale," chief military spokesperson Rear-Admiral Daniel Hagari said. "We are going on the offensive."

    Washington - which provides Israel with $3.8 billion in military assistance each year - said it was sending in fresh supplies of air defenses, munitions and other security assistance to Israel.

    The United States' top general warned Iran not to get involved in the crisis and said he did not want the conflict to the broaden. Iran makes no secret of its backing for Hamas and has applauded the weekend attack while denying any involvement.

    "We want to send a pretty strong message. We do not want this to broaden and the idea is for Iran to get that message loud and clear," General Charles Q. Brown, the chairman of the Joint Chiefs of Staff, told reporters traveling with him to Brussels.

    Governments including Italy, Thailand and Ukraine reported that their citizens had perished in the Hamas attacks. In Washington, President Joe Biden announced that at least 11 Americans had been killed and it was likely U.S. citizens were among those held hostage.

    "I have directed my team to work with their Israeli counterparts on every aspect of the hostage crisis, including sharing intelligence and deploying experts from across the United States government to consult with and advise Israeli counterparts on hostage recovery efforts," Biden said in a statement.

    As Israel conducted intense retaliatory strikes on Gaza, Defence Minister Yoav Gallant drew international condemnation by announcing a tightened blockade to prevent food and fuel from reaching the strip, home to 2.3 million people.

    "Depriving the population in an occupied territory of food and electricity is collective punishment, which is a war crime," Omar Shakir, Israel and Palestine Director at Human Rights Watch, said in a statement.

    Hamas-affiliated media said at least 20 people had been killed in Israeli strikes on houses in the Gaza Strip late on Monday. Palestinian media also reported that an Israeli air strike on a building in Gaza City had killed two Palestinian journalists and seriously wounded a third.

    Reuters was not immediately able to confirm the reports. The Israeli military had no immediate comment.

    As it rained, explosions and lightning lit the skies, and the sound of bombings mixed with thunder.
