    Israel says it’s destroyed Iran’s internal security headquarters in Tehran, as Iran fires more missiles towards Israeli territory.

    US President Donald Trump says he’s still weighing his options on US military intervention in the escalating hostilities.

    Earlier, Iran’s Supreme Leader Ali Khamenei said Iran won’t accept “imposed war”, and warns the US that any strikes on its territory will have “serious irreparable consequences”.

    The death toll from Israel’s attacks on Iran has risen to more than 240, including 70 women and children. At least 24 people have been killed in Iranian attacks on Israel.

    Israel’s war on Gaza has killed at least 55,493 people and wounded 129,320, according to Gaza’s Health Ministry. An estimated 1,139 people were killed in Israel during the October 7 attacks and more than 200 were taken captive.

    Israeli evacuation threat targets area around Iran’s Arak heavy-water nuclear reactor

    The Associated Press (AP) news agency reports that the target of Israel’s recent evacuation threat in the vicinity of Arak and Khondab cities is Iran’s Arak heavy-water nuclear reactor.

    According to the AP, Iran had agreed under its 2015 nuclear deal with world powers to redesign the Arak facility to relieve proliferation concerns. Heavy water helps cool nuclear reactors, but it produces plutonium as a byproduct that can potentially be used in nuclear weapons.

    Iran has said its nuclear programme is for civilian purposes and Britain had previously been helping the Iranian government to redesign the Arak reactor to limit the amount of plutonium it produces, the AP reports.

    As part of negotiations around the 2015 deal, Iran agreed to sell off its heavy water to Western countries. Even the US purchased some 32 tonnes of heavy water for over $8 million in one deal, the AP reports.

    Israel’s air strikes have already targeted Iran’s nuclear site at Natanz, centrifuge workshops around Tehran and a nuclear site in Isfahan.

    The United Nations International Atomic Energy Agency (IAEA) has urged Israel not to strike Iranian nuclear sites.

    IAEA inspectors reportedly last visited Arak on May 14.

    Iran again extends airspace closure

    The IRIB state broadcaster says Iranian authorities have extended the cancellation of takeoffs and landings of domestic and international flights until 2pm today (10:30 GMT).

    Iran’s airspace has been closed since Israel launched its attacks on Friday. Israel, too, has closed its airspace.

    The closures have forced other governments to evacuate their citizens by land via neighbouring countries.

    Israel calls on Iranians to ‘evacuate’ targeted area in northwest

    Residents, workers and others present in an area in the vicinity of the cities of Arak and Khondab in the northwest of Iran have been threatened with attack by Israeli forces and told to flee or their lives will be “at risk”.

    Publishing a satellite map with a large red target area covering buildings on the ground, the Israeli military said it was active in the area, targeting Iranian “military infrastructure”.
