Israel and Iran launched fresh attacks on each other Sunday, killing scores of civilians and raising fears of a wider conflict, and US President Donald Trump said it could be ended easily while warning Tehran not to strike any US targets.In Washington, two US officials said that Trump had vetoed an Israeli plan in recent days to kill Iran's Supreme Leader Ayatollah Ali Khamenei.Israel's military said several sites were hit by the latest Iranian missile barrage Sunday, with firefighters reporting a residential building struck on the country's Mediterranean coast."Homefront Command Search and Rescue teams have been dispatched to several hit sites in Israel, following the latest barrage from Iran," the military said.The fire services, meanwhile, said rescuers were heading to a building on the coast that sustained a "direct hit".Israel's first responders agency, the Magen David Adom, published footage of its teams deployed in the coastal city of Haifa, showing several cars on fire and a residential building whose facade was torn off by a blast.Paramedic Shira Gur said she was dispatched to a city in north Israel where "a building and vehicles were reported to be on fire due to a rocket impact."Israel on Friday launched an aerial assault to destroy the Iran's defence capabilities and cripple its nuclear programme, hitting nuclear and military facilities, and killing top commanders, atomic scientists and dozens of civilians.Sirens rang out across Israel after 4 pm Sunday in the first such daylight alert, and fresh explosions could be heard in Tel Aviv.In Iran, images from the capital showed the night sky lit up by a huge blaze at a fuel depot after Israel began strikes against Iran's oil and gas sector — raising the stakes for the global economy and the functioning of the Iranian state.Iran has not given a full death toll but said 78 people were killed on Friday and scores more have died since, including in a single attack that killed 60 on Saturday, half of them children, in a 14-storey apartment block flattened in Tehran.Trump said the conflict — which has raised fears of a wider conflagration — could be ended easily, while also warning Iran that the US could get involved if Iran hits any American targets.Regime change in Iran could be a result of Israel's military attacks on the country, Netanyahu said, adding that Israel would do whatever is necessary to remove what he called the "existential threat" posed by Tehran.Oil prices already shot up by 9% on Friday before Israel had struck any Iranian oil and gas targets.Iran has vowed to "open the gates of hell" in retaliation in what has emerged as the biggest ever confrontation between the longstanding enemies.The Israeli military warned Iranians living near weapons facilities to evacuate.An official said Israel still had a long list of targets in Iran and declined to say how long the offensive would continue.President Masoud Pezeshkian said Iran's responses will grow "more decisive and severe" if Israel's hostile actions continue.Some 22 of Iran's 270 ballistic missiles fired over the past two nights breached Israel's anti-missile shield, Israeli authorities say.
