CNN anchor Anderson Cooper and his colleagues were forced to evacuate live on-air Sunday after receiving an alert about an imminent Iranian missile strike in Tel Aviv. Cooper was in the middle of a segment with CNN correspondents Clarissa Ward and Jeremy Diamond when a siren blared at 3:02 a.m. local time. “These are the alerts that go out on all of our phones when you’re in Israel,” Cooper explained, noting the 10-minute warning before expected missile impact. Moments later, a verbal alarm ordered everyone nearby to seek immediate shelter. “We have about a 10-minute window to get down into a bomb shelter,” Cooper told viewers, adding that the team would continue broadcasting during the evacuation. Clarissa Ward asked, “Should we go down?” to which Cooper responded, “We should probably go down.” By 3:05 a.m., the team was seen removing their microphones and heading to safety. Cooper remarked that alerts like these are something residents of Tel Aviv have unfortunately become used to. The warning came just hours after U.S. B-2 bombers targeted three Iranian nuclear facilities.
