WASHINGTON (CNN) - Federal authorities have received a "plausible but unsubstantiated" report that al Qaeda may have discussed targeting transit systems in or around New York City, the Department of Homeland Security said.

"These discussions reportedly involved the use of suicide bombers or explosives" on subway or passenger rail trains, according to a joint DHS and FBI statement issued Tuesday.

"We have no specific details to confirm that this plot has developed beyond aspirational planning, but we are issuing this warning out of concern that such an attack could possibly be conducted during the forthcoming holiday season."
