U.S. officials have charged three men with attempting and plotting to provide material support to the militant group Islamic State.
All three suspects live in the New York City borough of Brooklyn. Two are citizens of Uzbekistan. The other is from Kazakhstan.
Officials say two of the men were planning to travel to Syria through Turkey. One of them was arrested at a New York City airport where he was attempting to get on a flight to Istanbul.
Officials in the United States have charged several other people recently with planning to support the Islamic State. A law enforcement official said there are currently Islamic State-related investigations in all 50 U.S. states.
