Libyan Ahmed Abu Khattala was sentenced Wednesday in Washington to 22 years in prison for his role in the 2012 Benghazi attack that killed a US ambassador and three others.
Prosecutors were unable to convince a jury that Khattala, leader of a militant group who had been photographed watching the attack on September 11, 2012, was directly to blame for the deaths of US Ambassador Christopher Stevens, a second State Department official, and two CIA contractor guards at the consulate and a CIA annex.
