Websites belonging to ​a Long Island town and the Ohio state government were hacked ​Sunday to broadcast ISIS propaganda, according to reports.

“Anti: Govt all word. You will be held accountable Trump, you and all your people for every drop of blood flowing in Muslim countries,” read the messages, according to local ABC affiliate WKYC.

The message was displayed on the ​the Brookhaven​, LI homepage, as well as the Ohio Department of Rehabilitation and Corrections, Casino Control, Ohio Office of Workforce Transformation. It even besmirched the websites of Ohio Gov. John Kasich and the ​state’s ​first lady.

The vandalization played out under a banner, reading: “Hacked By Team System DZ,” while the bottoms of the now-blackened pages declared “I love Islamic State.”

A link to the System Dz Facebook page is included as well.

The pro-ISIS group, which USA Today has described as a group of “anti-Israeli Arab teenagers,” has been behind other cyber attacks in recent months, including sites across France, Israel, and other countries.

Ohio Treasurer Josh Mandel took to Facebook to decry the offense.

“OH Dept of Corrections website right now, this is what you see,” the post reads. “Wake up freedom-loving Americans. Radical Islam infiltrating the heartland.”
