Eden Prairie's Web site was hacked on Sunday, The Star Tribune said.
Students who entered the site saw; a video, a picture of a Turkish flag and a handgun, KSTP said.
The words; "This was hacked by a silent assailant," were on the web page, said KSTP.
"Then it said something in Turkish," student Paul Rairamo told KSTP. "It was followed by some strong language, then the word 'Israel.'"
The schools Web site will remain shut down until the problem is solved. The school is among the 100 Web sites that have been hacked world-wide, KSTP said.
