Iran has launched missiles toward Israel, Israeli officials said Tuesday, shortly after the U.S. warned an attack was imminent. Israeli military spokesperson Rear Adm. Daniel Hagari said around 7:30 p.m. local time in Israel that missiles had just been launched from Iran. Sirens have been sounded across Israel, according to the military. Hagari added that Israeli civilians should remain vigilant and follow orders from authorities, which have sent messages to phones and directed people to safe zones. He said air defense systems are fully operational and ready to intercept any missiles. "The IDF is doing and will continue to do everything necessary to protect the civilians of Israel," he said, referring to the Israel Defense Forces. "The IDF is fully prepared for both defense and offense at peak readiness." A White House senior official warned earlier Tuesday morning that Iran was preparing an imminent attack, which comes just hours after Israel began raids into southern Lebanon targeting the Iranian-backed militant group Hezbollah. Defense Secretary Lloyd Austin also spoke with Israeli Minister of Defense Yoav Gallant earlier Tuesday, when the two discussed the “imminent” threat of an Iranian attack against Israel.   “Secretary Austin made it clear that the United States is well-postured to defend U.S. personnel, allies, and partners in the face of threats from Iran and Iran-backed terrorist organizations and is determined to prevent any actor from exploiting tensions or expanding the conflict in the region,” according to a readout of the call from Pentagon press secretary Maj. Gen. Pat Ryder. The two also “discussed the severe consequences for Iran in the event Iran chooses to launch a direct military attack against Israel.” And former President Trump quickly commented on the attacks Tuesday afternoon. “Look at the World today — Look at the missiles flying right now in the Middle East, look at what’s happening with Russia/Ukraine, look at Inflation destroying the World. NONE OF THIS HAPPENED WHILE I WAS PRESIDENT!” he wrote. Updated: 1:23 p.m.
