U.S. officials are investigating a cyberattack on water systems in Metropolitan Council facilities in Minnesota, with preliminary assessments suggesting Iran is likely responsible. The U.S. Environmental Protection Agency (EPA) and the FBI are involved in the investigation.

While the attack targeted industrial control systems, investigators emphasized that there were no indications that any water supply had been rendered unsafe to drink or that public health had been compromised. The incident highlights the growing concern over cyber threats to critical infrastructure.

Details about the specific methods used in the attack have not been disclosed, but the focus on Iran comes amid broader tensions between the two countries. The investigation is ongoing, and officials are working to determine the full extent of the breach and to bolster defenses against future attacks.
