A one-time associate of Osama Bin Laden died in New York on Friday while awaiting trial for allegedly plotting the 1998 bombings of U.S. embassies in Kenya and Tanzania.

Abu Anas al-Libi, 50, was captured in Libya by U.S. commandos in Oct. 2013 and brought to New York where he was due to stand trial. He had been wanted for more than a decade and there was a $5 million reward for his arrest. Al-Libi had pleaded not guilty.

The al Qaeda terror suspect has been in poor health and suffered liver disease as a result of hepatitis C, according to published reports.

In a court filing, U.S. Attorney Preet Bharara said that al-Libi was taken from the Metropolitan Correctional Center to a New York hospital "due to sudden complications arising out of his long-standing medical problems."

Bharara added that his condition "deteriorated rapidly" and despite the care provided to him, al-Libi passed away.

"We understand that, in addition to his counsel, an imam was with al-Libi at the hospital and that appropriate arrangements are being made with his family," Bharara wrote.

A spokesman for Bharara declined comment. An FBI spokesman did not immediately return a request for comment.

Al-Libi's attorney Bernard Kleinman had recently said his client's health was deteriorating. Kleinman did not immediately return a call for comment Saturday about al-Libi's death.
