In Iran’s capital city, the streets are empty, businesses closed, communications patchy at best. Panicked masses spend restless nights on the floors of metro stations as strikes boom overhead. The country is just under a week into a fierce Israeli blitz to destroy the country’s nuclear program and its military capabilities. Thousands have fled Tehran, spending hours in gridlock as they head toward the suburbs, the Caspian Sea, or even Armenia or Turkey. But others are stuck in high-rise apartment buildings. They worry and so do their relatives elsewhere.
