Haniffa Bin Osman, 55, of Singapore, pleaded guilty Thursday in U.S. District Court in Baltimore to conspiracy to provide material support to a designated foreign terrorist organization and money laundering.

“Osman is the third defendant to plead guilty to conspiracy to provide material support to a designated foreign terrorist organization, and three defendants have pleaded guilty to attempting to illegally export arms,” Maryland U.S. Attorney Rod Rosenstein said.
