Fox News says a Muslim group, in collaboration with a Brooklyn imam once investigated as a possible co-conspirator in the 1993 World Trade Center bombing, paid $48,000 to run Islamic advertisements on the city’s subway cars this September.

The ad campaign — known as the “Subway Project” — was designed to inform people about Islam and dispel common misconceptions about the religion, a representative for the Islamic Circle of North America told FOXNews.com. The story was first reported Monday in the New York Post and later rereported by FoxNews.

But the effort to plaster 1,000 subway cars with pro-Islamic messages has given new life to the controversy that has surrounded the radical imam, Siraj Wahhaj, who is promoting the campaign.

Wahhaj was once listed by prosecutor Andy McCarthy as an unindicted person who may have been an alleged co-conspirator in the deadly 1993 terror bombing of the World Trade Center.
