Another man is facing charges in New York City that he was involved in a plot to recruit U.S. fighters to join the Islamic State group.

Akmal Zakirov becomes the fifth defendant charged in an indictment filed in federal court in Brooklyn. The name of his attorney wasn't immediately available Thursday.

Prosecutors accused Zakirov of plotting to pay for one of his co-defendants to fly to the Middle East to join the Islamic State group. The man was intercepted at Kennedy airport in February before he could board a flight to Turkey.

The other men have already pleaded not guilty to conspiring to provide material support to a foreign terrorist organization. All are emigrants from the former Soviet republics of Uzbekistan and Kazakhstan.
