President Donald Trump made an early exit from the G7 summit on Monday and is heading back to Washington as tensions with Iran reach a critical point. In less than a day, Trump went from calling a nuclear deal with Tehran "achievable" to urging residents of the Iranian capital to evacuate.

Aerial attacks between Israel and Iran continued overnight into Tuesday, marking a fifth day of strikes following Israel's Friday attack. That surprise operation hit at the heart of Iran's nuclear program, striking key facilities and killing several nuclear scientists as well as high-ranking military leaders, according to Israeli officials.
