A data-driven look at 640 recorded strikes across Iran — what, where, and when.

Iranian citizens are trying to keep themselves safe during the war with the U.S. with a crowdsourced iOS app, but most users are located outside of Iran's borders, out of direct danger. Warning citizens about airstrikes and troop maneuvers are critical during a war.

JAKARTA - In the midst of conflict and information limitations, Iranian citizens take extreme measures. They build their own crowdsourced air attack warning system. The platform called Mahsa Alert emerged as an emergency solution when there was no official government system to provide public warnings.

For a long time, the Iranian government has treated free internet access as a privilege that is extended by the state to those willing to carry its message and withheld from everyone else. Around four hours after Israeli and American strikes began, internet traffic collapsed by 98 percent — a near-total blackout.

As the U.S. and Israel round out a fifth week of war with Iran, some 93 million civilians living inside Iran are stuck in a conflict zone without a missile alert system or access to the internet. Another 4 million people of Iranian origin worldwide are cut off from their friends and family still in the country.

Since the 2026 U.S. war with Iran began more than three weeks ago, United States military forces have allegedly attacked more than 9,000 sites, creating a climate of fear and constant uncertainty for Iranians in Tehran and across the country.
