A Virginia teenager who ran a pro-ISIS Twitter account and helped a friend travel to Syria to join the Islamist group was sentenced this morning to 11 years and four months in prison. Ali Amin, 17, faced a maximum sentence of 15 years.

The Washington Post reports that Amin, who pleaded guilty in June to conspiring to provide material support to terrorists, tweeted approximately 7,000 times from the apparently pro-ISIS account @AmreekiWitness, which had more than 4,000 followers and has since been suspended. He also introduced his friend Reza Niknejad to ISIS members online, and helped the 18-year-old travel to join the militia in Syria.

From the Post:

Prosecutors wrote in their sentencing memo that Amin had affected “worldwide security” and ruined his friend’s life. They alleged that Amin radicalized Niknejad, though they conceded the older man “made his own decisions.”

“Under a best-case scenario, Niknejad will return to the United States to be prosecuted and incarcerated for his activities,” prosecutors wrote. “It is far more likely, unfortunately, that he will accomplish the goal that this defendant set out for him; martyrdom in the name of ISIL.”

Prosecutors, who described Amin as a “prolific, sophisticated Islamic State supporter,” as the Post put it, sought the maximum sentence of 15 years; Amin’s defense attorneys asked for a six-year, three-month sentence.

Before he was sentenced, Amin read a statement to the court. “I made my decisions, and I am prepared to bear their fullest consequences,” he said. He also renounced ISIS, saying it “takes the greatest and most profound teachings of Islam and turns them into justifications for violence and death.”
