PRISTINA, Kosovo — Musli Musliu’s Facebook page looks much like any other 20-something’s profile: He posts selfies along with videos uploaded from YouTube, and he has an app for playing Texas Hold ‘Em with his friends. But his profile is not actually one of a typical millennial. The videos Musli posts call for jihad, urging his friends to join the fight against the enemies of Islam. One photo shows a man with a balaclava covering his face. In another, a man holds an assault rifle with a bullet belt wrapped like a scarf around his neck.
His family says that the photos were likely taken in the Middle East, where Musli and his brother, Valon, both natives of Kosovo, traveled to join militant groups. In April, Musli called home to inform his family that Valon had been killed during the Islamic State’s campaign in Fallujah. Valon, who would have been 22 now, studied in a madrasa, or Islamic high school, in Kosovo’s capital, Pristina, before moving to Egypt to study at Al-Azhar University. (The family did not discuss Musli’s background.) Eight months after leaving for the Middle East, Valon came home to visit his family, who tried to talk him out of going back.
