A former Libyan militia leader was convicted Tuesday of terrorism charges for his role in the 2012 attacks on the U.S. embassy in Benghazi, Libya, that left U.S. Ambassador J. Christopher Stevens and three other Americans dead. He was, however, acquitted of 14 other charges, including murder, The New York Times reported. Ahmed Abu Khattala, 46, now faces up to 60 years in prison, having been convicted on four counts, including conspiracy to provide material support for terrorism. He is the first person charged and successfully prosecuted for their role in the attacks.
