War has emptied the usually traffic-jammed streets of Iran¡¯s capital, but Islamic republic authorities have filled them with checkpoints and security forces as they tighten their grip on the population.

After the United States and Israel launched a war against Iran on Saturday, killing its supreme leader and urging Iranians to ¡°take over¡± their government, celebrations at Ayatollah Ali Khamenei¡¯s death were quickly stifled.

Iranians have since found themselves caught between the bombs and their government as authorities deploy heavy security and cut off the population from the outside world with an internet blackout.
