U.S. President Donald Trump on Monday night cut short his participation at the G7 summit to leave Alberta, Canada, and return to Washington, D.C., to focus on the conflict between Israel and Iran. French President Emmanual Macron announced Trump had made a cease-fire offer between the two countries.

Israel unleashed airstrikes across Iran for a third day and threatened even greater force as some Iranian missiles evaded Israeli air defenses to strike buildings in the heart of the country.

The headquarters of the Islamic Republic of Iran Broadcasting in Tehran was hit by an Israeli airstrike during a live broadcast Monday, June 16.

The Iranian regime faces pressure as Israel strikes military targets, with Iranian Americans advocating for the overthrow of what one Iranian American describes as a "paper tiger regime."

President Trump rejected an Israeli plan in recent days to kill Iran's Supreme Leader Ayatollah Ali Khamenei, a senior U.S. official told USA TODAY.

As airstrikes play out between Israel and Iran, there are many Americans who are concerned about loved ones caught in the war zone.

Iran fired a new wave of missile attacks on Israel early Monday, killing at least five people, while Israel claimed in the fourth day of the conflict that it had now achieved “aerial superiority” over Tehran and could fly over the Iranian capital without facing major threats.

The greatest risk the oil markets face is that Iran retaliates against Israel airstrikes by closing the Strait of Hormuz, which is critical to global energy shipments.
