Six people have been charged with providing money and equipment including U.S. military uniforms to foreign fighters joining al Qaeda, Nusra Front and Islamic State in Syria and Iraq, the U.S. Justice Department said on Friday.

The six are Bosnian natives living in Missouri, Illinois and New York. Five of them were arrested in the United States and charged with conspiring to provide material support and resources to terrorists. The sixth person is overseas, the department said in a statement.

Members of the group conspired to provide money and equipment - including U.S. military uniforms, combat boots, tactical gear, military surplus goods and firearms accessories - to be used to commit crimes outside the United States, according to a federal grand jury indictment made public by the Justice Department.

It said people in Turkey and Saudi Arabia acted as intermediaries who received the money and property from the defendants in the United States and transferred them to militants fighting with groups in Syria, Iraq and elsewhere.

The group transferred thousands of dollars over the past two years to purchase equipment for a man identified as Abdullah Ramo Pazara and other foreign fighters traveling to join battles in Syria, Iraq and elsewhere, the indictment said.

In one message last year, two of the accused parties discussed buying a night-vision optic with a built-in camera for recording killings while fighting in the Middle East, according to the indictment.

The indictment said members of the group used telephones and Facebook and other social media to send and receive messages, using fictitious names and code words including 'Lions,' 'Bosnian brothers' and 'mujahids.'
