Hospitals are on alert after social media posts allege plans for a coordinated, multi-city terrorist attack in the coming weeks. The terrorist group ISIS-K (Islamic State of Iraq and ash-Sham–Khorasan Province) is said to be planning to put IEDs onto vehicles and put them in close range of hospitals. The post states that the primary targets are mid-tier cities with low-security facilities.

The alert has been given as a precaution and the FBI is working the case. They plan to provide updates as more details emerge and recommend hospitals heighten staff awareness of the threat.

Terrorist organizations typically do not announce attacks in advance, but public posts like this one could inspire individuals to commit violence, and hospitals around the country are increasing their responses to suspicious vehicles.
