(if I did link right)
Weren’t these the people who were in the photo at Times Square with one of the bombers? I don’t remember if it was the older one or the younger one, but at least two of these people (the one in the center and the one to his left) were in that photo.
They both look Asian, but there are a lot of Asian Muslims and there are also a lot of Russian citizens from the remote Stans who look Asian.
