A judge in the US on Wednesday sentenced a Libyan militant to 22 years in prison for his role in the 2012 attacks on US compounds in Benghazi that killed four Americans, including Ambassador Chris Stevens.
In November 2017, a jury in Washington convicted 47-year-old Ahmed Abu Khattala of multiple terrorism-related charges but found him not guilty of murder.
The convictions could have carried a maximum sentence of life in prison.
Prosecutors accused Abu Khattala of heading an extremist militia and directing the attacks that killed Stevens and three others.
But prosecutors also acknowledged that they lacked evidence of Abu Khattala actually firing any weapons.
The Benghazi attacks and their aftermath quickly became a divisive political issue in American politics.
Republicans accused then-President Barack Obama and then-Secretary of State Hillary Clinton of intentionally misleading the public and stonewalling congressional investigators.
The final report by a Republican-led congressional panel faulted the Obama administration for security deficiencies at the Libyan outpost and a slow response to the attacks.
The report, however, found no wrongdoing by Clinton.
However, those allegations continued to follow Clinton during her 2016 presidential campaign.
