NEW YORK, (Reuters) – An ex-New Yorker has been found guilty of going to the Middle East in order to recruit Islamic State fighters. He also obtained weapons to aid the terrorist militants that U.S. authorities call a terrorist organization.

Mirsad Khandic, aged 40, faces up to 30 years in prison when he is sentenced. Prosecutors claimed that he was an “high-ranking ISIS member” who traveled to Syria for the purpose of joining in 2013.

According to prosecutors, he helped others from Western countries, such as a New Yorker and an Australian 18-year old, travel to Syria.

Court records show that a jury convicted him Tuesday on six charges, including support material to ISIS.

Breon Peace (the top Brooklyn federal prosecutor) said Wednesday that Kandic’s actions are directly related to terrorist attacks and significant losses of lives.

Kandic’s lawyers didn’t immediately reply to my request for comment.

Kandic was an American legal permanent resident. He was detained in Bosnia, and was extradited to America in 2017.

Prosecutors claim Kandic was the operator of a private Telegram marketplace where Telegram users could sell firearms and military gear.
