US Secretary of State Rex Tillerson said that the preamble to the Iran nuclear deal implied that it would lead to a more stable Middle East region and said Iran remains a source of instability.
"Regrettably, since the agreement was confirmed we have seen anything but a more peaceful stable region, and this is a real issue," he told reporters. "That why we talk about Iran defaulting on these expectations, since those expectations have not been met."
He accused Tehran of military support of Syria’s President Bashar Assad, of influencing the situation in Yemen and Iraq, as well as of aggressive actions against US Navy ships in the Persian Gulf, the AFP reported.
Tillerson also mentioned Iran's cyber activity and missile tests.
