Trump says he’s open to meeting Rouhani on the sidelines of the UNGA, in what would be the first-ever meeting of presidents of the United States and the Islamic Republic.

For another, the blood is as bad as ever, with Tehran suggesting that the US was responsible for a terrorist attack on a memorial parade in Ahwaz over the weekend.
