A number of government websites in the US state of Ohio, including that of Governor John Kasich, have been hacked to display a pro-IS message.
The hacking was carried out by a group calling itself Team System DZ.
The Ohio governor's website was down for maintenance for some time on Sunday, before coming back online.
The message in the hacking attack contained an Arabic symbol and was written mainly in the black and white used in the flag of so-called Islamic State.
The message on Mr Kasich's site also played an Islamic call to prayer.

The message read: "You will be held accountable Trump, you and all your people for every drop of blood flowing in Muslim countries."
A spokeswoman for Mr Kasich, Emmalee Kalmbach, said in a statement: "As soon as we were notified of the situation, we immediately began to correct it, and will continue to monitor until fully resolved."
A number of other officials website were affected, including those of the Ohio Office of Health Transformation and the Ohio Department of Medicaid. They later came back online as well.
