One or more Iranians witnessed North Korea’s recent missile tests, deepening U.S. concerns about growing ties between two countries with troubling nuclear capabilities, a top U.S. official said Thursday.
I guess this really doesn’t surprise me, though it’s the first I’ve heard of a specific Iran – North Korea connection.
