The operation has targeted key military and nuclear sites, with reports indicating that strikes have expanded to include military facilities in western Iran.

TEL AVIV, Israel (AP) — President Donald Trump on Monday posted on his social media site an ominous message calling for the immediate evacuation of the Iranian capital of Tehran while he’s in Canada attending the G7 summit.

U.S. President Donald Trump urged all of Iran's capital to evacuate "immediately," saying in a social media post that Iran would not be allowed to have a nuclear weapon.

Buildings three blocks away from the site of an overnight Iranian missile impact in Tel Aviv showed signs of damage, including cracked windows, on Monday. Closer to the impact site, businesses and apartments were largely bombed out. A 15-story high-rise overlooking the impact site over a parking lot was left entirely windowless.

Iranians say they are caught between their country's regime and Israeli destruction as the conflict intensifies.
