Federal authorities want to seize a Potomac mosque and two Prince William County properties owned by a nonprofit Muslim organization they say funnels cash to a bank that helps fund Iran’s nuclear program.

According to court documents filed Thursday, authorities want to take control of a 36-story New York City office tower, four mosques, including the one in Potomac, and two properties in Prince William County owned by the Alavi Foundation. Prosecutors say the foundation is a front for the Iranian government-owned Bank Melli.
