Latest on the conflict between Israel and Iran as Trump weighs

Tonight, sources familiar with classified assessments tell ABC News that President Trump is growing more comfortable with the idea of ordering a military strike on Iran's Fordow nuclear facility, a site dug nearly 300 feet into a mountainside. The president gathering his national security team twice in the last day. ABC News has learned the president has reviewed detailed strike options, telling senior advisors he supports the planning, but has not yet made the call. I may do it, I may not do it. I mean, nobody knows what I'm going to do. I can tell you this, that Iran's got a lot of trouble. This comes as Israel steps up its military campaign. The Israeli defense forces claiming responsibility for striking over 60 Iranian targets, including suspected nuclear research centers and weapons factories. President Trump has demanded Iran's unconditional surrender, but Iran's supreme leader is not backing down. The Ayatollah saying, surrender to what? The Iranian nation cannot be surrendered. We will not accept any kind of submission. He warned the U.S. would suffer irreparable consequences if it intervenes militarily. Warning sirens blaring across Israel again tonight, as missiles were seen over the skies of Tel Aviv and Jerusalem. Anti-war protesters gathering outside the White House tonight. My supporters are for me. My supporters are America first, they make America great again. My supporters don't want to see Iran have a nuclear weapon. Zorin Shah, ABC News, Los Angeles.
