WASHINGTON (AP) — President Donald Trump vetoed a plan presented by Israel to the U.S. to kill Iran’s Supreme Leader Ayatollah Ali Khamenei, according to a U.S. official familiar with the matter. The Israelis informed the Trump administration in recent days that they had developed a credible plan to kill Khamenei.

Israel’s attack on Iran was long in the making – the result of years of meticulous planning by Israel and days of high-stakes talks between Tel Aviv and Washington, officials told CNN.

Tehran has asked Qatar, Saudi Arabia and Oman to press U.S. President Donald Trump to use his influence on Israel to agree to an immediate ceasefire with Iran in return for Tehran's flexibility in nuclear negotiations,
