CHAPEL HILL, N.C. ? A recent University of North Carolina graduate was charged with nine counts of attempted murder Saturday, a day after authorities say he drove through a popular campus spot in an attempt to avenge Muslim deaths.

Derek Poarch, chief of the university police department, confirmed Saturday that Mohammed Reza Taheri-azar, a 22-year-old Iran native, told investigators he wanted to “avenge the deaths or murders of Muslims around the world.” Poarch would not provide any other details on the motive.

Taheri-azar also is charged with nine counts of assault.
