A Swedish professor suggested Israel was behind the bloody terror attacks committed by Norwegian terrorist Anders Behring Breivik this past July, stirring up controversy in the country. Research professor Ola Tunander of the Peace Research Institute Oslo (PRIO) published an article in the Norwegian academic journal Nytt Norsk Tidsskrift in which he called to further examine Brevik's motives. According to Tunander, it is possible that some country was behind the terror attacks, hinting that Israel might be that country.
