A former U.S. Army and National Guard soldier was allegedly communicating with and providing material and monetary support to a terrorist group operating in Syria, government prosecutors say.

Maria Bell, 53, of Hopatcong, NJ was arrested at her home by FBI agents. She was due to make her initial court appearance via video conference on Wednesday afternoon.

Bell is accused of providing material support to the al-Nusra Front, which is also known as al-Qaeda in Syria or al-Qaeda in the Levant. The al-Nusra Front is a Salafist jihadist organization fighting against Syrian government forces in the Syrian civil war. Its aim was to force President Bashar Assad from power and establish an Islamic state in the country.

Al-Nusra Front was formed in November 2012 and a month later the United States Department of State designated it a foreign terrorist organization. In April 2013, it became the official Syrian branch of al-Qaeda.

The group also goes by Hay’at Tahrir al-Sham (HTS) and now claims to be independent and not part of al-Qaeda. 

On Wednesday, Bell, a hospital analyst and political activist, was planning on flying to Egypt and then on to Istanbul, according to an FBI affidavit filed on Tuesday. That’s when authorities decided to arrest her. She had previously been stopped by the FBI from traveling to Turkey.

Prosecutors said Bell began using encrypted applications to communicate with and provide advice to the group starting in February 2017.

In communicating with al-Nusra Front members, Bell cited her professional experience in specialized weapons training while on active duty in the U.S. Army and Army National Guard, prosecutors said. She also offered to provide guidance concerning operational security issues, weapons purchases, and general military knowledge. However, her official record shows just eight months of Army service back in the 1980s, according to a report by NBC News.
