Exchanges of messages between Iran and the United States related to efforts to reach a preliminary memorandum of understanding have been halted for at least several days now, the semi-official Fars News Agency reported Tuesday, citing an informed source.
The source said recent media reports and statements by some Western officials portraying communications between Tehran and Washington as routine "do not reflect the current reality."
According to the source, message exchanges between the two sides regarding what has been described as an initial memorandum of understanding have been suspended for several days now.
The Iranian source said the latest message from Iran to Washington was a "public message" concerning Lebanon that received broad international attention.
